摘要

The rhenium(I) complexes [Re(O2CCF3)CO)(3)(L)] (1) and [Re(O2CCF3)(CO)(2)LL'] (L = Ph2POCH2CH2OPPh2: L' = PPhn(OR)(3-n); R = Me, Et; n = 0-2) (2a-f) have been synthesised by the reaction of the parent bromo derivatives with AgO2CCF3. These compounds have been characterized by microanalysis, IR, NMR, mass spectrometry and, in the cases of 1 and 2a, by X-ray diffraction. The metal is in a distorted octahedral environment with the trifluoroacetate ligand acting in a monodentate manner.
