A gold-catalyzed synthesis of tetrasubstituted 1,3-enynes fromhypervalent iodine(III) reagents and activated alkenes is reported. This reaction involves an in situ formed alkynyl Au(III) species and a subsequent direct C(sp2)–H functionalization of alkenes, offering 26 enynes in 62–92% yield with excellent functional group tolerance.
