Gold Catalysis: Isolation of Vinylgold Complexes Derived from Alkynes

Gold plated rings: N‐Propargylcarboxamides (1) when reacted with a gold complex containing the IPr N‐heterocyclic carbene ligand, delivers the first isolable vinylgold intermediates obtained from alkynes. [see Scheme; IPr=1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylide]
