beta -cyanoalkylsilane preparation using tetraalkylammonium halide supported on silica gel as catalyst

摘要

A process for the preparation of hydrolyzable beta-cyanoalkylsilanes. More particularly, this invention relates to the catalytic addition of silicon hydrides to alpha , beta -unsaturated olefinic nitriles to form beta -cyanoalkylsilanes. The present invention employs tetraalkylammonium halide supported on silica gel as a catalyst.
