- Abstract
- Reaction of the P-coordinated transition metal complexes [(Fp)Ph(2)PC=CR][BF4] (R = H, CH3, Ph, p-tolyl; Fp = CpFe(CO)(2)) with cobalt octacarbonyl at room temperature affords the cationic heterometallic complexes [(Fp)Ph(2)PC=CR{Co-2(CO)(6)}][BF4] (1-4) in high yields. A single-crystal X-ray structural analysis of 3 showed that the hexacarbonyldicobalt fragment is rr-bonded to the alkynyl group of the P-coordinated (diphenylphosphino)alkyne without significant interaction between the iron and cobalt fragments. Spectroscopic data for 1-4 and structural data for 3 suggest that the positive charge is mainly located on the iron fragment.
