SYNTHESIS AND REACTIVITY OF TRIFLATE SUBS TITUTED SILOXANE DERIVATIVES

The reaction of amino substituted siloxane derivatives with trifluorom ethanesulfonic acid leads under elimination of ammonium trifluorometha nesulfonate to the formation of siloxanyl triflates. The compounds are characterised by NMR-spectroscopy (Si-29, C-13, H-1). The synthetic p otential of these siloxanes is shown on selected examples. One interes ting point of view is the synthesis of silicon containing oligo- and p olymeres, in which siloxane and silylenealkine units are combined.
