Copper(I) tert-butoxide-promoted allylation of β-triphenylsilyl allylic alcohols via 1,3 Csp2-to-o silyl migration
The substitution of the silyl group in vinylsilanes by an allylic group proceeded when β-triphenylsilylallyl alcohols were treated with copper(I) tert-butoxide and allylic halides. This reaction is the first synthetic application of 1,3 Csp2-to-O silyl migration which provides a useful method for generation of vinyl anion equivalents.
Highly stereoselective and efficient hydrosilylation of terminal alkynes catalyzed by [RuCl2(p-cymene)]2
(Formula presented) With [RuCl2(p-cymene)]2 as a catalyst, extremely high regio-and stereoselectivity was observed in the hydrosilylation reaction of various terminal alkynes under mild conditions to afford β-(Z)-vinylsilanes in exce
