Revisit to the reduction of allylic chlorides to less substituted olefins by a low-valent chromium species in the presence of a proton source

Abstract Allylic chlorides have been reduced to afford less substituted olefins by a low-valent chromium species in the presence of an alcoholic proton source. This process certainly has synthetic benefits since the regio-selectivity of the reduction is high and the reaction conditions are mild and nearly neutral.
