Oxidation of amines in the presence of ruthenium complexes: Molecular oxygen and iodosylbenzene as oxidants
The authors report here the characterization of the related complex with R = p-CH3OC6H4. They report also the oxidation of secondary amines with molecular oxygen catalyzed by Ru(PPh3)3 Cl2 and Ru(DMSO)4Cl2. A study has also been made of the oxidation of primary and secondary amines using iodosylbenzene, PhIO, as the oxidant. It is found that PhIO is a very active and selective oxidant in these reactions, its activity being negatively modified by the presence of Ru(PPh3)3Cl2.
