Synthesis,Structure and Reactivity of New Solvent (MeOH or Me 2 SO) Coordinated Rh(III) Complexes: A Cyclic Series of Chemical Transformations Involving RhCl 3 -mediated azo Cleavage
Reaction of RhCl3.3H2O with 2-(phenylazo) aniline, HL–NH2, in boiling methanol afforded three products [RhCl2 (L–NH2)(HL–NH2)], 1, [RhCl2(L–NH2)(H2NPh)] 2, and [RhCl2(L–NH2)(MeOH)], 3. The sequential transformation of 1 to 2 followed by 3 has been established where the –N=N– cleavage occurs during the conversion of 1 to 2. Further, treatment of 3 with HL–NH2 in dichloromethane furnished 1 to complete a reaction cycle.
