摘要：
Terminal fluoride complexes of the monovalent group 11 metals, supported by N-heterocyclic carbene (NHC) ligands, react with one-half equivalent of triphenylmethyl cation to form fluoride-bridged dinuclear cations. An improved preparation of the starting terminal fluorides is introduced. The crystal structures of the cations display bent M-F-M arrangements with large intermetallic separations. The bridging fluorides are highly labile, undergoing facile hydrolysis. The fluoride-bridged digold complex adds across an allene C=C bond to form a diaurated allylic fluoride. (C) 2014 Elsevier Ltd.
