摘要

A photocatalytic system to effect the Meerwein-Ponndorf-Verley reduction of carbonylic compounds to alcohols has been developed.The system comprises [Ru(bpy)_3]~(2+)as a photosensitizer,triethanolamine as a sacrificial electron donor,viologen as an electron acceptor,and the carbonyl compound and iPrOH as Meerwein-Ponndorf-Verley reagents.The photocatalytic reaction can be performed in neat iPrOH or in 1-butyl-3-methylimi-dazolium ionic liquid.Mass spectro-metric detection of the viologen hydride derivative VH~+ confirms that this species is the reducing agent responsible for the carbonyl compound reduction.The reaction intermediates involved in the photocatalytic system have also been characterized by laser flash photolysis.
