Effect of the structure of a silicon-containing nitrile on the course of its catalytic reduction

1. The hydrogenation of silicon-containing nitriles with the CN group in various positions relative to the silicon atom over skeletal catalysts was studied. 2. By this method (ω-aminoalkyl)silanes of various structure can be prepared in yields of up to 90%. 3. No (2-aminoalkyl)dialkoxysilanes and silacyclopentane-1-ethylamines were obtained by the catalytic reduction of the corresponding α-cyano silanes because of the occurrence of reaction with cleavage of the Si-C bond.
