2002organo-silicon compounds organo-silicon compounds S 0060 -168Silylation of Silyl-and Germylketenes Containing Bulky Substituents at the Silicon or Germanium Atom.-The title reaction affords the corresponding bis-organoelement-substituted ketenes [cf. (V), (VI)] or mixtures of these compounds with O-silylated acetylenes [cf. (IV)] in ratios depending on the size of the substituent on the heteroatom both in ketene and triflate and on the nature of the heteroelement. -(PONOMAREV, S. V.; ZOLOTAREVA, A. S.; EZHOV, R.
