Photochemical reactivity of [RuII(L)(CO)2Cl2] and [Me4N] [RuII(L)(CO)Cl3] (L = 2,2'-bipyridine or 4,4'-di(isopropoxycarbonyl)-2,2'-bipyridine) in acetonitrile and the redox properties of the resulting new complexes.
Photolysis of acetonitrile solns. of [RuII(L)(CO)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 quant. 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 behavior of all these compds. was studied by cyclic voltammetry at a platinum electrode, exhaustive electrolysis expts., and UV-visible absorption spectroscopy. [on SciFinder(R)]
