    Abstract: A novel process for the selective reduction of halonitroarenes in general and halonitroaromatic arenes in particular, without the hydrogenolysis of the C-Cl (where, X represents F-, Cl-, Br- and I) and the C-O-C bonds, in the presence of platinum based catalysts and ammonium formate. The invention makes the use of duel function of ammonium formate, as a hydrogen source for partial reduction (catalytic transfer hydrogenation) and as an additive controlling the hydrogenolysis side reactions during the completion of the reduction by high pressure catalytic hydrogenation using external hydrogen gas source. Uniqueness of the invention lies in the fact that either the catalytic transfer hydrogenation with ammonium formal e or high pressure catalytic hydrogenation in the absence of ammonium formate, when used alone result in lower purity of the said amine. This invention -product is used to synthesize intermediates for making antibacterial compounds.
