Treatment of [M(CO)4{(Ph2PCH2)2CMe(CH 2PPh2)}] (M = Mo or W) with neutral or cationic gold-(I) or -(III) derivatives afforded bi- or tri-nuclear complexes containing the triphosphine (Ph2PCH2)3CMe (tdppme) acting as a μ-P,P′,P″ ligand, a co-ordination mode poorly represented thus far. The binuclear derivative [(OC)4Mo(tdppme)AuCl] further reacts with 1 equivalent of Tl(acac) (acac = acetylacetonate) to afford [(OC)4Mo(tdppme)Au(acac)]. This complex acts as a deprotonating agent in reactions with various starting materials containing phosphines such as (Ph2P)2CH2 or (Ph2P)3CH, leading to the formation of trinuclear methanide complexes. The crystal structure of [(OC)4Mo(tdppme)AuCl] has been established by X-ray crystallography.
