Diversity-oriented synthesis of disubstituted alkenes using masked silanols
(Figure presented) The regio- and stereoselective synthesis and subsequent Hiyama cross coupling of pentafluorophenyldimethylvinylsilanes has been developed, thus providing a convenient and robust method for the diversity-oriented synthesis of (E)-, (Z)- and α-disubstituted alkenes from terminal alkynes. Pentafluorophenyldimethylvinylsilanes undergo cross-coupling reactions with excellent selectivity and in good yields, offering an attractive alternative to existing masked silanols.
