Rh(I) complexes of S-triazines and azobenzene were found to be 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 amounts 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. Kinetics was studied. Mechanism has been proposed and rate equation has been derived. Copyright Taylor & Francis Group, LLC.

The progressive addition of hydrazine and the following increasingly substituted hydrazines L (N2H4 Ia, H2NNHMe Ib, H2NNHPh Ie, H2NNMe2 Id, or MeHNNHMe Ic) to [Rh2(CO)4Cl2] resulted in the initial formation of [{Rh(CO)2Cl}2(μ-L)] 1 followed by the formation of cis-[Rh(CO)2L(Cl)] 2; analogous mononuclear complexes were formed directly on addition of the more heavily substituted hydrazines Me2NNMe2 IIf and H2NNPh2 IIg, but addition of 1,2-N2H2Ph2 IIIh to [Rh2(CO)4Cl] resulted in disproportionate of the hydrazine and formation of cis-[Rh(CO)2(NH2Ph)Cl] 3 and cis-[Rh(CO)2(PhN=NPh)Cl] 4. The above complexes have been spectroscopically characterised by IR and 13C/15N NMR measurements. X-Ray structural analysis on [{Rh(CO)2Cl}2(μ-L)] (L = H2NNHMe or MeHNNHMe) confirmed that L adopts a μ-η1:η1-mode of bonding with a cisoid arrangement of the Rh(CO)2Cl groups about the N-N bond.
