Metal hopping: Various alkynylstannanes were synthesized by the directreaction of Bu3SnOMe with terminalalkynes at room temperature in the presence of a ZnBr2 catalyst. Rather than acting as a Lewis acid, ZnBr2 was transmetalated with Bu3SnOMe to give Zn(OMe)2, which is key to the catalytic reaction.
