Reactions between R3PAuCl, NaOEt, and HC<*>CR' under mild conditions produce R3PAuC<*>CR' in excellent yield.When R' = H, a second step leading to the formation of R3PAuC<*>CAuPR3 can take place.Exchange reactions of ethynyl for chloride between the ethynylgold complexes and HgCl2, cis-, cis-, and R 3PAuCl have been monitored, revealing R3PAuC<*>CR' to be useful alkynylating agents.In the reaction with cis-, the first substitution step is non-specific.
