The first Au III carbene complex was prepared by reacting a geminal dianion with a (P,C) cyclometalated Au III precursor. Its structure and bonding situation have been thoroughly investigated by experimental and computational means. The presence of a high‐energy highest occupied molecular orbital (HOMO) centered at the carbene center suggests nucleophilic character for the Au III carbene complex. This unprecedented feature was confirmed by reactions with two electrophiles (PhNCS and CS 2 ), resulting in two types of C=C coupling reactions.
