Abstract

A rhodium complex derived from RhH(PPh₃)₄ and Me ₂PhP catalyzed the carbothiolation reaction of 1-alkylthio-1-alkynes and 1,4-diaryl-1,3-butadiynes giving (Z)-4-alkylthio-4-aryl-3-arylethynyl-3- buten-1-ynes. Terminal alkynes such as 1-decyne and (t-butylthio)acetylene underwent the carbothiolation reaction using a RhH(PPh₃) ₄-dppb catalyst. The reactions proceeded via cis-addition with C-C bond formation at the less hindered acetylene carbon.
