Facile and practical hydrodehalogenations of organic halides enabled by calcium hydride and palladium chloride

Herein, a convenient hydrodehalogenation method was described by employing less-explored calcium hydride as the reductant. A wide range of organic halides such as aromatic bromides, aromatic chlorides, aromatic triflates, aliphatic bromides and aliphatic chlorides were efficiently and selectively reduced to obtain the corresponding hydrocarbons. More importantly, monodehalogenation of trihalomethyl compounds in THF could provide various useful dihalomethyl products.
