Abstract: Aminobenzylamines are produced by catalytically reducing o-, m- or p-nitrobenzaldoxime in an organic solvent in the presence of a compound selected from the group consisting of (a) boric acid, phosphoric acid and/or anhydrides thereof, (b) CO2 gas and (c) an organic acid. The starting material, nitrobenzaldoxime is produced by reaction of the corresponding nitrobenzaldehyde with hydroxylamine.

Abstract: A process for preparing an aminobenzylamine comprises catalytically reducing a nitrobenzylamine of the general formula (I): wherein the nitro-group is located at the o-position, m-position, or p-position. As preferred embodiments of this process, there is disclosed a method for catalytically reducing in the presence of acids, and a method of using mineral acid salts of a nitrobenzylamine mixture obtained by nitrating benzylamine.

Abstract: 4-Fluorobenzophenone derivatives or 4,4'-difluoro-benzophenone are produced by effecting a halogen-fluorine exchanging reaction between the corresponding 4-halogeno-benzophenone derivatives or 4,4'-dihalogenobenzophenone and an alkali fluoride. The reaction is carried out by heating in an organic solvent. After distilling off the solvent from the reaction product mixture, the end product is isolated by extracting with a solvent. Alternatively the end product is isolated by distillation.
