Syntheses of a number of adducts of silver(i) (bi-)carbonate with triphenylphosphine, both mechanochemically, and from solution, are described, together with their infra-red spectra, 31P CP MAS NMR and crystal structures. Ag(HCO3):PPh3 (1:4) has been isolated in the ionic form [Ag(PPh3)4](HCO3) ·2EtOH·3H2O. Ag2CO3:PPh 3 (1:4) forms a binuclear neutral molecule [(Ph3P) 2Ag(O,μ-O′·CO)Ag(PPh3)2] (·2H2O), while Ag(HCO3):PPh3 (1:2) has been isolated in both mononuclear and binuclear forms: [(Ph3P) 2Ag(O2COH)] and [(Ph3P)2Ag(μ- O·CO·OH)2Ag(PPh3)2] (both unsolvated). A more convenient method for the preparation of the previously reported copper(i) complex [(Ph3P)2Cu(HCO3)] is also reported.

ArCuI compounds (Ar=phenyl, o-, m-, or p-tolyl) do not react with carbon dioxide at appreciable rate, but in the presence of triphenylphosphine in appropriate undergo insertion to give the corresponding carboxylato complexes ArCO2Cu(PPh3)2.In t

Carbon dioxide reacts with ROCu(PPh3)2 (R = C2H5, C6H5CH2; PPh3 = triphenylphosphine) to produce ROCO2Cu(PPh3)2.Hydrolysis or thermolysis of the alkylcarbonatocopper(I) complexes gives a binuclear carbonatocopper(I) complex (PPh3)2CuOCO2Cu(PPh3)2, which is further converted into a hydrogencarbonatocopper(I) complex n by the reaction with CO2 in most solvents.The IR spectrum of n shows association of the HOCO2Cu(PPh3)2 units through hydrogen bonds.The IR spectrum of n also reveals that the mode of the association depends on conditions of the crystallization of the complex.The reaction of (PPh3)2CuOCO2Cu(PPh3)2 with CH3I gives (CH3O)2CO and the reaction of n with C6H5NH2 affords C6H5NHCO2Cu(PPh3)2 in high yields.Carbon dioxide reacts also with an amidocopper(I) complex C6H5NHCu(PPh3)2 to yield a carbamatocopper(I) complex C6H5NHCO2Cu(PPh3)2.The reaction of CH3Cu(PPh3)2 (diethyl ether)0.5 with CO2 in the presence of HN(C2H5)2 affords (C2H5)2NHCO2Cu(PPh3)2.The isocyanate group of phenyl isocyanate is inserted into the C2H5O-Cu bond of C2H5OCu(PPh3)2 to give a (ethyl N-phenylcarbamato)copper complex.
