Cover Picture Retro-Cycloaddition Reaction of Pyrrolidinofullerenes (Angew. Chem. Int. Ed. 12006)код для вставкиСкачать
Cover Picture Nazario Martn,* Margarita Altable, Salvatore Filippone, Angel Martn-Domenech, Luis Echegoyen,* and Claudia M. Cardona Retro-cycloaddition of easily prepared pyrrolidinofullerenes affords quantitatively pristine fullerenes, and thus can be used as a new protection-deprotection protocol in the chemistry of fullerenes, as shown in the cover picture. In their Communication on page 110 ff., N. Mart n, L. Echegoyen, and co-workers report on this promising finding, which has already allowed the selective isolation of the Ih constitutional isomer of Sc3N@C80. Liquid Crystals In their Review on page 38 ff., T. Kato et al. explain the design of new liquid crystals through supramolecular approaches. Ordering principles and potential application are described. Imaging Agents The use of hyperpolarized xenon for the NMR detection of immobilized avidin analyte with high sensitivity is described in the Communication by C. Hilty et al. on page 70 ff. Boride Carbides The structures of Li2B12C2 and LiB13C2 are shown by H. Hillebrecht and N. Vojteer in their Communication on page 165 ff. to consist of a 3D framework of B12 icosahedra and C2 and CBC units, respectively, with Li cations in the voids.
