    1. Reactions of heavier main-group compounds with hydrogen, ammonia, ethylene and related small molecules (pages 238–255)

      Philip P. Power

      Article first published online: 16 DEC 2011 | DOI: 10.1002/tcr.201100016

      The reaction between hydrogen and a main-group compound under ambient conditions was first reported in 2005, and this unexpected result has been followed by numerous others which show that such reactivity is widespread in unsaturated and multiple bonded main-group species. These may react spontaneously not only with hydrogen, but also with ethylene, ammonia and related molecules. Illustrated here is the mechanism of the initial step of the activation of dihydrogen under ambient conditions by a main-group molecule (a digermyne).

    2. Structural and electronic properties of endohedral metallofullerenes (pages 256–269)

      Article first published online: 10 APR 2012 | DOI: 10.1002/tcr.201100038

      Endohedral metallofullerenes (EMFs) are a new class of metal-carbon hybrid materials formed by encapsulation of metals inside fullerene cavities. Structural determination of EMFs is of fundamental importance for understanding their intrinsic properties and the formation mechanism, and broadening their applications. An overview of the structure and chemistry of EMFs is presented with emphasis on: the determination of structures of paramagnetic EMFs, the first observation of the motion of cluster in a di-metal EMF, unambiguously established structures of carbide EMFs, recently obtained insoluble EMF species, and the chemical properties of various EMFs in terms of both covalent and supramolecular considerations as well as the dictating effect of internal metals.
