Abstract
Abstract The preparation of 2,6-difluoroaniline and 1,2-difluorobenzene from 1,2,3- trichlorobenzene is described. An isomeric mixture of 1-chloro-2,3-difluorobenzene and 2-chloro-1,3-difluorobenzene is obtained from KF exchange on 1,2,3- trichlorobenzene. Selective dechlorination of 1-chloro-2,3-difluorobenzene with H2 and Pd/C catalyst gives 1,2-difluorobenzene. 2,6-Difluoroaniline is obtained via ammonolysis of 2-chloro-1,3-difluorobenzene.
