Abstract
One of the azine ligands in fac-Re(CO)3L2Cl, L = 4-cyanopyridine or qu inoline, was found to be more labile than in other related Re(I) compl exes. Substitution of 4-cyanopyridine by 4-phenylpyridine in fac-Re(CO )3(4-cyanopyridine)2Cl was successfully applied to the preparation of fac-Re(CO)3(4-cyanopyridine)(4-phenylpyridine)Cl. The kinetics of the mixed-ligand complex formation was investigated and a reaction mechani sm is proposed.
