The preparation of η2-alkynecopper(I) complexes of the composition RCu(η2-alkyne)>, alkyne = tolan, dimethyl acetylenedicarboxylate, is described.LR- are anionic tris-chelating oxygen ligands of the type 3>-, R = OMe, OEt, O-i-Pr.The isonitrile complexes RM(CN-t-Bu)>, M = Cu, Ag, have been prepared from OMeCu(CO)> and OEt>2>, respectively.The silver carbonyl complex OEtAg(CO)> -1> forms in hexane and methanol solutions of OEt>2> under 1 atm of CO gas.The olefin complexes RCu(ba)>, ba = benzylidene acetone, have been prepared from PF6, NaLOMe, and ba and from the carbonyl complex OEtCu(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.
