摘要：

Photolysis of acetonitrile solutions of [RuII(LXCO)2Cl2] or [Me4N][RuII(L)(CO)Cl3] (L = 2,2'-bipyridine or 4,4'-di(isopropoxycarbonyl-2,2'-bipyridine) leads to the successive formation of the new complexes [Ru(L)(CO)(CH3CN)Cl2], [Ru(L)(CH3CN)2Cl2], and [Ru(L)(CH3CN)3Cl]+ by photosubstitution processes. However, [Ru(L)(CH3CN)2Cl2], unlike [Ru(L)(CO)(CH3CN)Cl2] and [Ru(L)(CH3CN)3Cl]+, cannot be obtained quantitatively with the complex having the unsubstituted 2,2'-bipyridine ligand. Moreover [Ru(L)(CH3CN)3Cl]+ cannot be produced at a significant rate for complexes with L = 4,4'-isopropoxycarbonyl-2,2'-bipyridine. The redox behaviour of all these compounds was studied by cyclic voltammetry at a platinum electrode, exhaustive electrolysis experiments, and UV-visible absorption spectroscopy.
