摘要:
A mononuclear complex (CO)3ReL2Cl (1a) (L = NH2CHMe2) and a dinuclear CO2 complex (CO)3L2Re(mu,eta1,eta1-CO2)Re(CO)4L (2) are prepared from the reaction of a carbamoyl complex, (CO)4ReL(CONHCHMe2) with H2O in CHCl3. The coupling of a proposed intermediate (CO)4LReCOOH with la is a viable process for the formation of complex 2. The structures of (CO)3ReL2Cl (1b) (L=NH2CH2CH=CH2) and 2 have been established by X-ray diffraction.
