The addition of aminosilicon hydrides and silazane hydrides to olefins and to dimethylaminodimethylvinylsilane in the presence of chloroplatinic acid was studied. n- Butylaminodimethylsilane and hexene-1 formed 2-n-butyl-ln-hexyl-l, 1, 3, 3- tetramethyldisilazane which diminished a. 3 the reaction proceeded to form n- butylaminohexyldimethylsilane. Dialkylaminodimethylsilanes and trisdiniethylaminosilane ...
