A novel reduction of diketones with i-RMgBr catalyzed by Cp2TiCl2 and deoxygenation of sulfoxides by Cp2TiCl2/Al system.
Alpha-diketones and beta-diketones react with Grignard reagents in the presence of a catalytic amount of Cp2TiCl2 to yield alpha-ketols and corresponding ketones respectively. Sulfoxides can be deoxygenated by Cp2TiCl2/Al system. The possible mechanisms are also discussed.
