Method of making 3-halopropyltrihalosilanes by hydrosilylation

Abstract

A method synthesizes at least one 3-halopropyltrihalosilane compound. The method includes I) at least one unsaturated compound selected from the group consisting of allyl halide and methallyl halide; and II) at least one H-silane selected from the group consisting of trihalosilane, methyldihalosilane and dimethylhalosilane. The reaction of the at least one unsaturated compound and the at least one H-silane is carried out in the presence of: III) a Karstedt catalyst and IV) at least one cocatalyst according to formula (A). In formula (A), R1 is an aryl group; each R2 is independently an alkyl group; and n is 0 or 1. A catalyst composition suitable for mediating a hydrosilylation reaction. A reactive composition is produced from the reaction products.
