BENZYLIDENE AND METHYLENE-BIS-SILYLTRIFLA TES AS NEW SYNTHETIC MATERIALS FOR ORGANOSILICON POLYMERS

The title compounds have been prepared by reaction of phenyl-, allyl- or amino-substituted disilylmethanes and disilylphenylmethanes with tr ifluoromethanesulfonic acid. New organosilicon oligomers and polymers are obtained in good yields and high purities from these silyltriflate s and lithium acetylides, triphenylgermyllithium or diphenylsilanediol /triethylamine. In these compounds the carbosilane units are connected by alkyne or siloxane bridges. The structures have been confirmed by NMR spectroscopy (Si-29, C-13, H-1) and elemental analysis.
