HYDRODEFLUORINATION OF TRIFLUOROMETHYL GROUP IN POLYFLUOROALKYLBENZENES Russian patent published in 2002 - IPC

Abstract RU 2182570 C2

FIELD: fluoroorganic chemistry, chemical technology. SUBSTANCE: compounds synthesized in reaction of hydrodefluorination are used as intermediate substances. Hydrodefluorination reaction of CF3-group is carried out with aluminium chloride and cyclic-C5- C6 or aliphatic-C5- C12 hydrocarbon in medium of chloroorganic solvent at heating from 30 to 80 C. Method provides the selective hydrodefluorination of CF3-group in polyfluoroalkylbenzenes using low-priced and available raw. EFFECT: improved method of hydrodefluorination, decreased cost. 1 tbl, 9 ex
