Diversity-Oriented Synthesis of Disubstituted Alkenes Using Masked Silanols
摘要:
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 alpha-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.

The addition of (pentafluorophenyl)dimethylsilane (I), bis(pentafluorophenyl)methylsilane (II) and tris(pentafluorophenyl)silane (III) to phenylacetylene catalyzed by hexachloroplatinic acid gave mixtures of α- and β-substituted styrenes in each case; the proportion of the α-isomer increased from (I)–(III).
