Anionic N<i>‐</i>Heterocyclic Carbenes That Contain a Weakly Coordinating Borate Moiety

Abstract

Piggyback ride: Anionic N-heterocyclic carbenes are presented that bear their negative charge in the form of a weakly coordinating anionic borate moiety in the backbone. This class of carbene can be used in silver-free routes for the preparation of neutral, single-source gold(I) catalysts, the performance of which is comparable with that of other cationic gold(I) catalysts in enyne rearrangements.
