ABSTRACT
While gold-mediated synergistic catalytic processes involving transmetalations with other metals are well understood, AuI /AuIII cycles in these reactions are rarely reported. Herein a gold-catalyzed direct alkynylation of cyclopropenes is enabled by two operating catalytic cycles, an oxidative catalytic cycle involving an alkynyl AuIII complex formed by oxidative addition and one involving a silver-mediated C-H activation.
