✦ Synopsis

Hydrosilylation of Acetylenes with Catalytic Biscobalthexacarbonyl

Complex and Its Application to Heteroconjugate Addition Methodology.

-Carbohydrate derived acetylenes (I) and (V) undergo efficient hydrosilylation in the presence of catalytic biscobalthexacarbonyl complexes. The phenylthioacetylenes (Ic) and (V) react completely regioselectively. The products [cf. (VI)] are precursors of vinylsulfones useful for heteroconjugate addition studies.
