The trans-[RuCl2(dppb)(bqdi)] and trans-[RuCl 2(dppb)(opda)] complexes (dppb = 1,4-bis(diphenylphosphine)butane, bqdi = o-benzoquinonediimine, and opda = o-phenylenediamine) were synthesized from the reaction of the mer-[RuCl3(dppb)(H2O)] aqua-complex with the opda ligand. The X-ray structural and electrochemical characterizations of the isolated compounds showed that this aqua-complex induces the oxidative dehydrogenation of the amine species (opda) to the imine form (bqdi) of the o-phenylene ligand during the synthetic procedure. In the presence of oxygen, the 31P{1H} NMR experiments confirmed that the trans-[RuCl2(dppb)(bqdi)] complex is the only product formed.
