Alkene, Alkyne, Isonitrile, and Carbonyl Complexes of Copper(I) and Silver(I) with Tris-Chelating Oxygen LigandsThe preparation of η2-alkynecopper(I) complexes of the composition [LRCu(η2-alkyne)], alkyne = tolan, dimethyl acetylenedicarboxylate, is described. LR are anionic tris-chelating oxygen ligands of the type [(C5H5)Co{P(O)R2}3]-, R = OMe, OEt, O-i-Pr. The isonitrile complexes [LRM(CN—t-Bu)], M = Cu, Ag, have been prepared from [LOMeCu(CO)] and [{AgLOEt}2], respectively, The silver carbonyl complex [LOEt}Ag(CO)] [v(C≡O) = 2147 cm-1] forms in hexane and methanol solutions of [{AgLOEt}2] under 1 atm of CO gas. The olefin complexes [LRCu(ba)], ba = benzytlideneacetone, have been prepared from [Cu(CH3CN)4]PF6, NaLOMe, and ba and from the carbonyl complex [LOEtCu(CO)] and ba. The coordination of the carbon-carbon double bond of ba at the LRCu fragment does not lead to a 1,4-addition of methyllithium to the α,β-unsaturated ketone.
