flow technique. The results
obtained demonstrate that diphenyltin dichloride and triphenyltin chloride
first adsorb onto the lipid bilayer surface, in a diffusion-controlled manner and
within a very short time (0.05 sec), whereas the membrane crossing was observed
in a minute’s time range. On passing from the outer to the inner surface of the
bilayer, organotins undergo desorption and enter the liposome interior, which
has been shown in the lipid monolayer desorption studies.

Two new cationic rhodium(I) complexes with
a chiral nitrogen-containing BINOL-based
diphosphite or phosphonite ligand have been
synthesized. They were evaluated in the hydroformylation of styrene and/or the hydrogenation of prochiral olefins and displayed good
activities but zero or low enantioselectivities.

In this work a simple method to phosphorize the surface of nanometric particles
of crystalline zirconia in an acetic acid
environment is described. The particle size
is in the range 40–60 nm and the proton
conductivity is of the order of 10−3 S cm−1
(measured on powder mixed with micro-fine
teflon) at room temperature.

-thiophene carbaldehyde and 1,1-bis(5-formyl2-furyl)silacyclo-pentane/-hexane and their thiosemicarbazones have been
synthesized. Thiosemicarbazones of 5-(1-methylsilacyclohexyl)furfural and 5(1-methylsilacyclopentyl)furfural were very active (1.0–4.0 µg ml−1 ) in vitro
against human fibrosarcoma HT-1080 and mouse hepatoma MG-22A cells.

tris(3-thienyl)-, and tris(5-chloro-2-thienyl)-, have been synthesized and characterized. Crystal structures and cytotoxicity
against Artemia salina and a few tumour
cell lines have been determined.

The 1 : 1 reaction of triphenyltin chloride with potassium N-[(3,5-dibromo2-hydroxyphenyl)methylene]valinate
leads to the formation of the title
compound by means of a facile Sn–C
bond cleavage process. The complex
contains trans-O2 SnC2 N and transO2 SnC3 distorted trigonal bipyramidal
geometries linked by a bridging carboxylate group. The compound exhibits good
cytotoxicity and antibacterial activity.
