Rh(I)-S-Triazene Complexes as Effective Homogeneous Recyclable Catalyst for Catalytic Hydrogenation of Organic Substrates

Download this article as: 

Rh(I) complexes of S-triazines were found very efficient towards the catalytic hydrogenation of alkenes, alkynes at normal pressure and at room temperature. Reduction of aromatic nitrocompounds, benzaldehyde and benzil were observed in appreciable amount only at high pressure and at high temperature. No diminished catalytic activity was observed even after 6-8 repeated catalytic runs. Profound effect was observed on the rate of reduction in presence of extra ligand without affecting the nature of yield, both under normal and high pressure conditions.
