Treatment of 5,5'-dilithio-2,2'-dithiophene with (dimethylamino)methylsily bis(triflate)-or a, vbis(triflate)-substituted trisilanes gave poly[5,5'-(silylene)-2,2'-dithienylene]s in high yields. The amino-silyl bond was cleaved selectively by triflic acid, leading to triflate-substituted derivatives

The highly reactive silyl triflates R 4-n Si(OSO 2 CF 3 ) n are valuable materials in organosilicon chemistry. Numerous new triflate derivatives of mono-, oligo-and polysilanes were prepared by stepwise substitution of trifluoromethanesulfonyl groups for phenyl groups or other leaving groups. Conver

The synthesis of a polymer-supported silyl triflate and subsequent functionalization with enolizable ct,[~unsaturated aldehydes and ketones to form silyloxydienes is reported herein. This novel route is ideal for the generation of substrates for solid-phase Diels-Alder reactions. The silyl triflate
