Not only aesthetically appealing: The
motif of the double-stranded helix (see
picture) is found in DNA, which is able to
store and process “information”. It
inspires scientists to search for ways to
mimic not only its fascinating structure
but also to develop helical systems with
different functionalities and properties,
with which one day, likewise, information
storage and processing could be
achieved.

The unusual suspects: By using a series of
ruthenium clusters of the type [{Ru3O(mCH3COO)6(CO)L’}(m-l){Ru3O(mCH3COO)6(CO)L’’}] (see picture) it has
been possible to identify the existence of
charge-transfer isomers and establish
them as identifiable chemical entities that
exist in dynamic equilibrium.

Heterogeneous Catalysts
Living in isolation: Single-site heterogeneous catalysts offer a widely applicable
strategic principle for the design of new
mono- and bifunctional catalysts. They
combine the merits of homogeneous and
heterogeneous processes and permit the
preparation of high activity regio-, shape-,
and enantioselective solid catalysts. The
picture shows a spatially constrained
organometallic, RhI-based enantioselective catalyst.

Unusual octahedral hexamers built up

trimers (see figure), form the basis of a
novel three-dimensional cobalt isophthalate obtained by a solvothermal
route. This structure provides a new
example of the concept of scale chemistry,
in which an {Na6Co6O26} “super octahedron” is connected in a classical ReO3
architecture.

The unique structure of a highly ordered
pyrolytic-graphite (HOPG) surface is
employed as a template to fabricate large
random arrays of metal-nanoband electrodes. This process is achieved through
selective blocking of the basal-plane
HOPG (A) with a polymer film (B),
followed by metal coating (C) and
cleavage of the metal layer from the
HOPG substrate (D; see picture).

Linking Rings through Diamines and
Clusters: Exploring Synthetic Methods for
Making Magnetic Quantum Gates
Polymer clay for chemists: High strengths
and high fracture energies of polymeric
hydrogels have been demonstrated by
incorporating a substantial amount of
nanodispersed inorganic clay during the
in situ free-radical polymerization of Nisopropylacrylamide. By varying the
amount of clay used, mechanical properties as well as the swelling and transparency of the nanocomposite (NC) could be
controlled (see picture; NC20 contains
more clay than NC5).

Fabrication of Random Assemblies of
Metal Nanobands: A General Method
Cage Compounds
Gates leading from cages: Linked paramagnetic cage complexes could potentially be used as quantum gates for
quantum information processing. Experiments demonstrate that it is possible to
link octanuclear {Cr7Ni} rings through
both organic and metal–organic fragments into supramolecular dimers (see
structure; Cr green, Ni light green, Cu
orange, F yellow, O red, N blue, C black).
Acid test: Macrocyclic compounds that
comprise a 9,10-anthracene subunit
linked by a C2-symmetric peptidomimetic

chain (see formula) are useful as fluorescent probes in a pH range of biomedical
interest. Changes in the size of the
macrocycle (n = 3,4,6,8) produce a shift in
the pKa values. Experiments with live
mouse macrophage cells show the selective localization of the probe in the acidic
organelles (see differential interference

Dielectric Properties of Porous Molecular
Crystals That Contain Polar Molecules
Simply lowering the temperature changes
a polarizable molecular system, which
consists of H2O and CH3OH inserted into
the porous crystal [Mn3(HCOO)6] (see
structure; Mn pink, C gray, O red), into a
nonpolarizable one. Although a large drop
in the dielectric constant was observed
around 120 K, reminiscent of a
liquid$solid phase transition of the guest
molecules, the anisotropy cannot be
explained by a simple liquid model of the
guest molecules.
Microfluidics
The problem of miniaturizing the mixing
process is a barrier to the advance of
microfluidic technology. Fluorescence
lifetime imaging is a powerful technique
for the quantitative mapping of mixing in
microfluidic systems, providing information essential to the design and evaluation
of next-generation devices. With the use of
a pulsed laser (B), mixing in a microfluidic
cell (A) can be measured with fluorescence (C); a sample image is shown
(right).

The Internal Structure of Helical Pores
Self-Assembled from Dendritic
Dipeptides is Stereochemically
Programmed and Allosterically Regulated
Keeping nature under control: The internal structure of helical porous protein
mimics self-assembled from hybrid dendritic dipeptides is programmed by the
stereochemistry of the dipeptide and
regulated allosterically. This is the first
example of a synthetic helical porous
supramolecular structure that is stable
both in solution and in the solid state, and
that is created by a sequence of events
related to those encountered in nature.

Just add CH3CN and stir! Four building
blocks taken in a multicomponent reaction (MCR, see picture; Tf = trifluoromethanesulfonyl) afford a b-aminoacetal
adduct, which can be further diversified by
post-condensation reactions. The modular character of this approach, the simplicity of the building blocks used, and the
structural diversity attained render this
process attractive for combinatorial as
well as target- and diversity-oriented
synthesis.

Artificial a helices prepared by the replacement of a hydrogen bond between
residues i and i + 4 with a carbon–carbon
bond can stabilize biologically relevant
peptides in helical conformations (1,
internal constraint shaded in gray). a Helices based on hydrogen-bond surrogates
that mimic Bak BH3 (2, yellow) can bind
their expected protein receptor, Bcl-xL
(2, green), with high affinity and resist
proteolytic degradation.

nontoxic, and nonimmunogenic. The cationic saccharide–peptide hybrid copolymers were also shown to be effective in
compacting and transferring plasmid
DNA into cells.
An efficient and highly diastereoselective
intramolecular Diels–Alder reaction is the
basis of a concise asymmetric synthesis of
the potent antibacterial natural product
abyssomicin C (see formula). The complexity of the target structure was reduced
to three fragments and required two
carbonyl addition reactions to achieve key
bond formations.

Highly Enantioselective Pd-Catalyzed
Allylic Alkylations of Acyclic Ketones
Pocket the difference: Highly enantioselective allylic alkylation of simple acyclic
ketones is carried out by using a Pd
catalyst with a “chiral pocket” ligand 1
(see scheme). The addition of a Lewis acid
such as AgBr and the selection of one
enolate form over another dramatically
affect the enantioselectivity of the
reaction.
Surprising rearrangements in a rigid
system: A cyclopropyl ring is formed
unexpectedly when a trienone substrate is
subjected to the Nazarov cyclization (see
scheme). The participation of the unconjugated alkene unit present in the sub-
strate might be a consequence of the
complete torquoselectivity of the initial
electrocyclic closure. A subsequent rearrangement by a homo-1,5-hydrogen shift
occurs cleanly to give the final product.

highly crystalline structures (see image)
have been obtained, and these perform
better than “normal” LT-LiCoO2 as intercalation electrodes in lithium batteries.

Delocalization in heterocycles: Reaction
of hexaphenylstannole with excess lithium

crystals. The aromaticity of the dianion
was examined by NMR spectroscopy, Xray analysis (see picture), and calculations. The dianion has considerable aromatic character and is reported to be the
first tin-containing carbocyclic aromatic
compound.
Thrifty catalysis: Tungsten carbide microspheres with high surface area and CO
chemisorption capacity were prepared by
heating mixtures of a resorcinol–formaldehyde polymer and ammonium metatungstate. Platinum supported on these
microspheres (see electron micrograph)
shows higher activity than the commercial
catalyst with 20 % Pt–Ru (1:1) on C for the
electrooxidation of methanol.
Take the rough with the smooth: Conducting silica microspheres with different
morphologies—rough, dotted, and
smooth (see picture)—have been rapidly
synthesized in an ionic liquid under
various experimental conditions. The
conducting property of the silica particles
is attributed to the presence of entrapped
molecules of ionic liquid and water.

Some sentences in the meeting review of ADHOC 2005 in Cologne were incorrect at the
time of press.
Page 6102, column 1, line 11 should read: To gain better insights, model systems with
well-defined active sites are being developed; on the other hand problems are
approached with the aid of kinetic measurements, sophisticated isotope-labeling
experiments, molecular probes, and especially computational chemistry which allows
the discussion of structure–activity relationships and can either support or reject
proposed mechanisms.
Page 6102, column 3, line 6 should read: On the other hand, A. Griesbeck (University of
Cologne, Germany) described how 1O2 with the aid of tetraarylporphyrin-loaded
polystyrene can be used for ene reactions and [4þ2] cycloadditions, and how it can even
be “made chiral” through organocatalysts.
Page 6103, column 2, line 7 should read: these effect the oxidation of bromide to
bromonium ions, which in turn can be reacted under nonacidic conditions with olefins
and aromatic compounds.
Page 6103, column 3, line 5 should read: The latter, however, are apparently stabilized by
POM ligands; their use recently afforded the synthesis of a Pt=O complex as described by
C. L. Hill (Emory University, Atlanta, USA), and now he reported the isolation and
characterization of the first Pd=O complex, K9Na4[(O=PdIV-OH)WO(OH2)L2]
(L = [PW9O34]9).
Page 6103, column 3, line 21 should read: Altogether, there is still great interest in the
oxidation of methane, the simplest yet most resistant C1 hydrocarbon source.
Page 6104, column 1, line 27 should read: … R. Hage (Unilever, The Netherlands)…
Page 6104, column 1, line 29 should read: The lecture given by G. Reinhardt (Clariant,
Germany) made it clear that there is not, and yet cannot be, a panacea for the bleaching
industry.
Page 6104, column 3, line 22 should read: The mechanistic understanding was
broadened, refined, and even renewed, and many novel systems have been developed.
Page 6104, column 3, last sentence: The pronounced relation to application was
underscored by the fact that this year’s meeting was, for the first time, organized jointly
by both the industrial and academic spheres as well as through the strong participation
and generous support of industry (especially BASF).
The Editorial Office apologizes for the oversight.
