The catalytic transfer hydrogenation studies on several arylhydrazones, prepared by coupling aryldiazonium salts with diethylmalonate and acetyl acetone have been carried out. It has been found that even under a variety of reaction conditions the reduction of diethyl mesoxalate-2-onitrophenylhydrazone or pentane-2,3,4- trioxo-3-o-nitrophenylhydrazone in anhydrous formic acid as a solvent and as a hydrogren donor with 10 per cent pd-C as a catalyst produces the N-formyl derivative of the free amino compound.
