inyl silanes are valuable synthetic precursors to various useful small organic molecules and polymeric organosilicon materials.[1] Consequently,the hydrosilylation of alkynes, arguably the most direct and atom-economical route to vinyl silanes,has become an area of intense investigation in the past few decades.[2] However,despite the significant

High cis stereoselectivity is observed for the reaction of the alkynes 12 (R = alkyl or aryl) with (TMS)3SiH, initiated by Et3B/O2 at room temperature (Scheme 6). On the other hand, radical-mediated silyldesulfonylation of various (E)-vinyl sulfones 14 with (TMS)3SiH provides access to (E)-vinyl silanes 15 (Scheme 6) [23,24].

Also, although the oxidative conditions employed for generation of the active organosilane species are similar to the ones used in Tamao–Kumada and Fleming oxidation of silanes to alcohols (including vinyl silanes to aldehydes and ketones), which involve cleavage of the C–Si bond, 19 we did not observe conversion of the vinyl silanes 2 and ...

On the other hand, radical-mediated silyldesulfonylation of various (E)-vinyl sulfones 14 with (TMS) 3 SiH provides access to (E)-vinyl silanes 15 [23,24]. These highly stereoselective reactions presumably occur via a radical addition followed by β-scission with the ejection of PhSO 2 • radical.
