Metal complexes [M(acac)(PPh3)] act as deprotonating agents in the reaction with equimolar amounts of [CH{PPh2(X)}3] to give the neutral complexes [M{C(PPh2(X))3}(PPh3)] [M = Ag, X = O (1) or S (2); M = Au; X = O (3) or S (4)]. The crystal structures of 2 and 3 have been established by X-ray crystallography. In the structure of 2 (two independent molecules) the suver(I) atoms display a distorted tetrahedral coordination by phosphorus (of PPh3) and three sulfur atoms. In complex 3 the gold(I) atom exhibits linear coordination by phosphorus of PPh3 and the carbon atom of [C{PPh2(O))3]-. The reaction of [CH{PPh2(X)}3] with [Ag(CF3SO3)] or [Ag(CF3SO3)(PPh3)] (molar ratio 1:1) leads to [Ag(CF3SO3){CH(PPh2(X))3}] [X= O (5), S (6)] or [Ag{CH{PPh2(S))3}(PPh3)](CF3SO 3) (7), respectively.
