Cyclization/hydrosilylation of functionalized diynes catalyzed by a cationic rhodium bis(phosphine) complex

Journal Article (Journal Article)

The catalysis of cyclization/hydrosilylation of 5,5-dicarbomethoxy-2,7-nonadiyne and triethylsilane by the cationic rhodium complex [Rh(BINAP)(COD)]+BF4- [BINAP = (±)-2,2′-bis-(diphenylphosphino)binaphthyl] was presented. The (E,Z)-1,1-dicarbomethoxy-3-ethylidene-4-(1-triethylsilylethylidene)cyclopen tane in 77% yield with ≤50:1 isomeric purity was formed by the catalysis. It was observed that the cationic rhodium bis(phosphine) complexes were active catalysts for the hydrosilylation of functionalized alkynes.
