A number of 2,6-disubstituted and 2,3,6-trisubstituted anilines have been prepared via the selective para dehalogenation of the corresponding anilines. Modification of the substituents on the amino nitrogen demonstrates that the selectivity is derived from steric rather than electronic effects. The effects of the choice of formate hydrogen donor, Pd catalyst, solvent, and temperature upon the efficiency and selectivity of the dehalogenation are discussed.
Process for the selective reduction of the 4-halogen in 2,4-dihaloanilines

Substituted 2-haloanilines are prepared from the correspondingly substituted 2,4-dichloro- or 2,4-dibromoanilines by selectively reducing a chloro or bromo substituent para to a protected amino group in the presence of the same halogen as an ortho substit
