Transition metal compounds, and specifically transition metal compounds having a tetradentate and/or pentadentate supporting ligand are described, together with methods for the preparation thereof and the use of such compounds as hydrogenation and/or hydrosilylation catalysts.

produced from 1-hexene and SiH4. Ethylsilane was produced from ethylene and SiH4. The reaction mechanism involving SiH4 and the alkyl anion, which is formed by the interaction between LiAlH4 and the olefin, has been proposed.
Iron complexes formulated as Fe(terpy)X-2 (terpy = 2,2':6',2 ''-terpyridine derivatives; X = Cl, Br) were prepared and their catalytic activities for hydrosilylation of olefin with hydrosilane were examined. Although Fe(terpy)X-2 did not show catalytic activity, the treatment of Fe(terpy)X-2 with NaHBEt3 caused catalytic activity. The influence of substituents in terpy on the catalytic activity was examined, and it was found that some complexes with an unsymmetrically disubstituted terpy selectively produced 1-silylalkane with quite high catalytic activity. In the reaction of 1-octene with PhSiH3, the double-hydrosilylation product Ph(1-octyl)(2)SiH was selectively obtained.
