Reaction Steps

Tetrakis(bromopropyldimethylsiloxy)silane was synthesized by the following reactions starting from tetrakis(dimethylsiloxy)silane. Thus, allyloxytrimethylsilane was reacted with tetrakis(dimethylsiloxy)silane in the presence of a platinum 1,1,3,3-tetramethyl-1,3-divinyldisiloxane complex as catalyst to produce tetrakis(trimethylsiloxypropyldimethylsiloxy)silane, from which the trimethylsiloxy group was subsequently eliminated by the action of excess methanol to give tetrakis(hydroxypropyldimethylsiloxy)silane. Methanesulfonyl chloride was then reacted in pyridine with the tetrakis(hydroxypropyldimethylsiloxy)silane to give tetrakis(methanesulfonyloxypropyldimethylsiloxy)silane, which was subsequently reacted with sodium bromide in DMF to give tetrakis(bromopropyldimethylsiloxy)silane:
