摘要
The novel iridium(I)-pybox complexes [Ir(Ln)(n)-{kappa N-3,N,N-(S,S)-i-Pr-pybox}][PF6] (n = 2, L = eta(2)-C2H4 (1), eta(2)-MeO2CC CCO2Me (2); n = 1, L = CO (3)) have been synthesized. The treatment of complex 1 with HCl or allyl chloride under very mild conditions results in the stereoselective formation of the complexes [IrClH(eta(2)-C2H4){kappa N-3,N,N-(S,S)-i-Pr-pybox}][PF6] (4) and [IrCl(eta(3)-C3H5){(KN)-N-3,N,N-(S,S)-i-Pr-pybox}][PF6] (5). The structures of complexes 1 and 5 have been determined by X-ray diffraction analyses.
