1, 3-Dimethyl-2-phenylbenzimidazoline (DMBI) has been found to be a powerful, chemoselective, and useful reducing agent for mild reductive dehalogenation of a variety of a-halo carbonyl compounds (halo= Br, C1, F) and acid chlorides. The reduction of a-halo ketones, aldehydes, esters, lactones, and carboxylic acids with this new reagent in ether is quite selective and clean and generally proceeds in almost quantitative yields at moderate ...
