Organosilicon polymers containing (SiH2) or (SiH2)2 units have been prepared via silyltriflate intermediates. Two methods of the formation of silicon-hydrogen bonds are described. Polysilaethylene [SiH2-CH2- ]n has been prepared by ring-opening polymerization of tetraphenyl-1,3-disilacyclobutane followed by a protodesilylation reaction with triflic acid and reduction with LiAlH4. The reaction of H2Si(OTf)2 or (TfO )H2Si- SiH2(OTf) with organolithium or organomagnesium compounds gave poly(silyleneethyne)s [(SiH2)n-C≡C]n and poly(silylenephenylene)s [(SiH2)n-C6H4 -]n. These polymers may serve as suitable precursors for ceramic materials. The TGA studies gave remarkably high ceramic yields. NMR measurements (29Si, 13C, 1H) indicate an regular alternating arrangement of silicon atoms and organic groups in the polymer backbone.
