Two for one gold: Factors governing the formation of isolable digold(I) ó,¿-acetylide complexes are given (see scheme), indicating the general tendency of phosphine¿AuI precatalysts to form this type of complexes, which are involved as reaction intermediates in gold(I)-catalyzed reactions. Mechanistic insights into the intermolecular hydroamination of aniline and terminal alkynes catalyzed by gold(I) have shown the role of a fluxional, cationic ó,¿-digold alkynide complex as one of the intermediates in the formation of imines.
