Photoassistance in Reactions of the cis-(Bis(2,2'-bipyridyl))(carbonyl)(formyl)ruthenium(II) Cation with Protic Reagents

摘要

Cationic ruthenium complexes with C_1 ligands have been implicated as important intermediates in photocatalytic or electrocatalytic reductions of CO_2 to formate and other products, yet little is known about their chemistry. Prior to the recent reportof the synthesis of cis-Ru(bpy)_2(CO)(CHO)+ PF_6~-(1; bpy = 2,2'-bipyridyl) by Tanaka et al., we had also synthesized the compound and begun a study of its reactions. We now describe our observations on the unusual reactions of 1 and suggest explanations for these reactions.
