FeCl3·6H2O-catalyzed selective reduction of allylic halides to alkenes with concomitant oxidation of benzylic alcohols to aldehydes

Iron Catalysis in Organic Synthesis

“…The hydrodehalogenation of 1,3-diaryl-3-halopropenes with benzylic alcohols as reductants has been achieved in the presence of catalytic amounts of iron(III) chloride hexahydrate (Scheme ) . The reaction was carried out in toluene at 80 °C and provided the corresponding olefins in high yields.…”
