Herein, the easy-to-handle B(C6F5)3-catalyzed ionic transfer hydrosilylation of various alkenes using 3-silylated cyclohexa-1,4-dienes is described. The corresponding hydrosilylated alkenes are obtained in high yields.
Often, work in the laboratory with Me3SiH and Me2SiH2 is prohibited because of safety considerations. Since the silylated cyclohexadienes are precursors for the analogous gaseous hydrosilanes, which are generated in situ by a B(C6F5)3-catalyzed release of these hydrosilanes, this protocol is a safe alternative for the hydrosilylation of alkenes.
