Abstract :Since the obtained chiral alcohols are rather useful as well as biologically active compounds, reduction of ketones to their respective alcohols is a crucial topic in synthetic chemistry. Thus, a new phosphinite ligand was synthesized by the interaction of cationic species N-vinyl imidazolium insert ignore into journalissuearticles values(1); with PCy2Cl. This phosphinite ligand in combination with [Ruinsert ignore into journalissuearticles values(η6-p-cymene);insert ignore into journalissuearticles values(µ-Cl);Cl]2 and Irinsert ignore into journalissuearticles values(η5-C5Me5);insert ignore into journalissuearticles values(μ-Cl);Cl]2 gave active catalytic systems for transfer hydrogenation reaction. Under optimum circumstances, ruthenium complex insert ignore into journalissuearticles values(3); showed rather high conversion reduction reaction of acetophenone. Reversibility of the transfer hydrogenation reaction was found to be low under these reaction circumstances.
