摘要
[IrCl(diphosphine)](2) {diphosphine = BINAP (1a) and BPBP (1b)} were obtained as extremely air-and moisture-sensitive crystals. The structure of 1a has been determined by X-ray analysis. Complex 1a reacted easily with two equivalents of triphenylphosphine to give IrCl(binap)(PPh3) 2a quantitatively. Complexes 1a and 1b can activate RO-H groups easily and catalyze transfer hydrogenation of alkynes in methanol. On the contrary 2a does not react with methanol even at 55 degrees C.
