Abstract

While gold-mediated synergistic catalytic processes involving transmetalations with other metals are well understood, Au I /Au III 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 Au III complex formed by oxidative addition and one involving a silver-mediated C−H activation.
