New complexes of the fac-{(CO)3Re+} fragment bearing a diaminediphosphine ligand
摘要:
The mono- and binuclear hydride compounds fac-[ReH(CO)(3)L) (1a) and [(ReH(CO)(4)}(2)(mu-L)] (1b) have been prepared by reaction of [ReH(CO)(5)] with Ph2PN(CH3)(CH2)(2)N(CH3)PPh2 (L) under UV light. Protonation reactions of the hydride compound la with equimolar amounts of HSO3CF3 or HCl yielded the triflato or the chlorido compounds fac-[Re(OSO2CF3)(CO)(3)L) (2) and fac-[ReCl(CP)(3)L] (3), respectively. The compounds have been characterised by elemental analysis, IR and NMR spectroscopic data, and mass spectrometry. Their structures have been confirmed by X-ray crystallography.
