The selective cleavage of phenylsilane by triflic acid gives silyltriflates. The removal of phenyl groups in Ph3SiH and carbosilane polymer (Ph2SiCH2CH2CH2)n with one to two equiv of triflic acid leads to formation of mono- and disubstituted silyltriflate ester bonds. Reaction with allylmagnesium bromide produces corresponding derivatives with good yields. An organosilane dendrimer with allylated carbosilane polymer has been synthesized up to G3 using repetitive allylation hydrosilylation cycles.
