摘要：

A new formyl complex, cis-Ru(phen)(2)(CO)(CHO)(PF6) (8), has been characterized, and some of its reactions have been compared with those of its bipyridyl analogue. Reactions of 8 with MeOH can he photoassisted and lead to a metalloester, 7; reaction rates are comparable to those of the bipyridyl analogue. Reactions of 8 in DME/H2O require Oz and can be photoassisted; the reactions lead to a mu(2)-eta(2)-type CO2-bridged complex, 10. Reactions of 8 with water are slower than those of the bipyridyl analogue and allow observation of an intermediate metallocarboxylic acid, cis-Ru(phen)(2)(CO)(COOH)(PF6) (6), which has been structurally characterized. A related CO2-bridged complex, cis,cis-[Ru(phen)(2)(CO2)Ru(bpy)(2)(CO)](2PF(6)) (11), has also been prepared and structurally characterized; its spectral properties support the formulation of 10 and its bipyridyl analogue.
