Cover Picture: Solar-Driven Incorporation of Carbon Dioxide into α-Amino Ketones (Angew. Chem. Int. Ed. 47/2012)



original image

Carbon dioxide was incorporated into α-amino ketones through a consecutive process consisting of a solar-energy-harvesting photocyclization reaction and a CO2 incorporation reaction driven by the harvested energy. The single-flask operation described by M. Murakami and co-workers in their Communication on page 11750 ff. produced amino-substituted cyclic carbonates, thereby presenting a simple model of the chemical utilization of solar energy for CO2 incorporation.

In their Commumnication on p. 11722 ff., Y. Rubin, A. Hirsch, and co-workers report the synthesis of pentaarylated azafullerene derivatives and their multihydro intermediates. A triaryldihydroazafullerene derivative is the first crystallographically characterized hydroazafullerene.

Mass Spectrometry

In their Communication on page 11832 ff., T. Müller, R. G. Cooks, and A. Badu-Tawiah investigate the Claisen–Schmidt condensation of 1-indanone and 4-chlorobenzaldehyde by electrospray-ionization mass spectrometry.

Heterogeneous Catalysts

In their Communication on page 11736 ff., I. Hermans and co-workers report a convenient preparation of Sn-β by solid-state ion exchange. The product has more favorable catalytic properties than Sn-β prepared by other routes.
