A cis-dioxoruthenium(VI) complex as active oxidant of chloride and organic substrates; preparation, characterization, and reactivity of cis-[RuVI(6,6′-Cl2bpy)2O2]2+(6,6′-Cl2bpy = 6,6′-dichloro-2,2′-bipyridine)
Abstract
Oxidation of cis-[RuII(6,6′-Cl2bpy)2(OH2)2]2+ with CeIV gave cis-[RuVI(6,6′-Cl2bpy)2O2]2+, isolated as the diamagnetic ClO4– salt, which rapidly oxidizes Cl–(to Cl2) and a wide variety of organic substrates (tetrahydrofuran to butyrolactone and cyclohexane to cyclohexanone).
