Vinyl trimethylsilane

Cycloaddition reactions of vinyl trimethylsilane with C -glycosyl nitrones gave moderate to good yields (67%-74%). Estimation of diastereoselectivities from isolated yields showed total endo preference for the reaction of the D-galacto nitrone. High endo preference was observed for the D-ribo analog, but exo preference for the D-xylo one (814).

The vinyldisilane (XXVIII) undergoes chloroplatinic acid-catalyzed hydrosilation with trimethylsilane with great ease at 40° C to give (/J-tri-methylsilylethyl)pentamethyldisilane in 93% yield, which can also be obtained in 80% yield by the addition of pentamethyldisilane to vinyl-trimethylsilane in the presence of tra r-dichloro(ethylene)(pyridine)-platinum(II) as catalyst in benzene at 45° C (128). 

The simplest compound in this series, 1-phenylthio- 1-trimethylsilyl ethylene 45, was conveniently prepared by Magnus and co-workers either by reaction of a-lithio vinyl phenyl sulfide 46 with trimethylsilylchloride,53 or by addition of arylsulfenyl-chloride to vinyl trimethylsilane followed by elimination of hydrogen chloride54...

Preparative Methods prepared by reaction of 2-(trimethylsilyl) ethanesulfonyl chloride (accessible from the commercially available sodium salt of the corresponding sulfonic acid or starting from vinyl trimethylsilane) with gaseous ammonia (eq 1). ... 

Direct alkylation has been achieved in special circumstances. Thus 2-(trimethylsilyl)ethyl sulfides, obtainable from alkylation of 2-(trimethylsilyl)ethanethiol or by radical addition of thiols to vinyl trimethylsilane, react with a-glycosyl bromide with the assistance of Ag(I) activation to offer a general synthesis of 8-thioglycosides. Yields generally vary (34-99%), and the fi a ratio can be quite high (eq 10). ... 

More recently, Gacal and coworkers used Wilkinson s catalyst in the hydrosilylation of polyisoprene-f)/ocfe-poly(vinyl trimethylsilane) (PIP-6-PVTMS)." They achieved 80% hydrosilylation of the PIP unit and then...
