| Abstract: | A new reductive reaction is discovered in the system of titanium involving titanates of carboxylic acids ArCOCOOTi(OR 1) 3 and RLi, its mechanism is investigated in detail. The new reduction is proved to mostly result from the migration of hydrogen from OR 1 group to carbonyl group similar to the reduction of Meerwein-Ponderf-Verley. It is also concluded that RLi reagents facilitate the reaction in two manners. |
