Pd(II) complexes of S-Triazines and anthranilic acid were found very efficient towards the catalytic hydrogenation of organic nitrocompounds, alkenes, alkynes, etc. No diminished catalytic activity was observed even after 6-8 repeated catalytic runs. Profound effect on the rate of reduction and nature of yield were observed in presence of extra ligand. Kinetics were studied. Mechanism has been proposed and rate equation has been derived.
