Gui, Jingjing published the artcileFacile and practical hydrodehalogenations of organic halides enabled by calcium hydride and palladium chloride, Quality Control of 93-04-9, the publication is Organic Chemistry Frontiers (2021), 8(17), 4685-4692, database is CAplus.
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 RBr (R = 4-(dimethylamino)phenyl, 4-aminonaphthalen-1-yl, quinolin-5-yl, etc.), aromatic chlorides R1Cl (R1 = naphthalen-1-yl, 3-carboxy-5-methoxyphenyl, 2-[2-(cyclohexa-1,5-dien-1-yl)ethenyl]phenyl, etc.), aromatic triflates R2Otf (R2 = 2-methylquinolin-8-yl, 2-nitrophenyl, 2-acetylnaphthalen-1-yl, etc.), 1-(2-(4-bromo/chlorobutoxy)phenyl)ethan-1-one were efficiently and selectively reduced to obtain the corresponding hydrocarbons e.g., Phenyl(pyrrolidin-1-yl)methanone. More importantly, monodehalogenation of trihalomethyl compounds R3CXY2 (R3 = benzenesulfonyl, 3-oxo-1-phenyl-3-(thiophen-3-yl)propyl, N-(naphthalen-1-yl)carbamoyl, etc.; X = Br, Cl; Y = Br, Cl, F) in THF could provide various useful dihalomethyl products R3CHY2.
