A novel reduction of diketones with i-RMgBr catalyzed by Cp2TiCl2 and deoxygenation of sulfoxides by Cp2TiCl2/Al system

Abstract

α-diketones and β-diketones react with Grignard reagents in the presence of a catalytic amount of Cp 2 TiCl 2 to yield α-ketols and corresponding ketones respectively. Sulfoxides can be deoxygenated by Cp 2 TiCl 2 /Al system. The possible mechanisms are also discussed.
