Carbonyl gold(I) bromide was obtained in solutions of halogenated hydrocarbons by (a) absorption of CO by in the presence of cyclohexene as a halogen abstractor, (b) carbonylation of ; (c) carbonylation of AuBr.The compound has been studied by spectroscopic methods in solution, including NMR measurements at variable temperature.Both and undergo a rapid exchange process with dissolved CO.The low stability of with respect to its decomposition to AuBr(s) prevents the isolation of the carbonyl bromide of gold(I).The present findings confirm the trend to lower stability in the sequence Cl > Br > I already established for the carbonylhalogeno derivatives of palladium(II) and platinum(II).

Gold(I) halides have been obtained from Au2Cl6: a) with cyclohexene as halogen acceptor (AuCl); b) by halide exchange with i-Pr-Br, followed by treatment with cyclohexene at low temperature (AuBr); c) by halide exchange with i-Pr-I at room temperature (AuI).Carbonylation of AuBr in dichloromethane or treatment of Au2Br6 with CO and cyclohexene in 1,2-dibromoethane yielded AuBr(CO), characterized by IR and 13C NMR spectra in solution, the latter at low temperature
