AbstractThe synthesis of [RuIII(salen)(X)(Y)]n [n = -1, (X)(Y) = (CN)2; n = 0, (X)(Y) = (PPh3)(PBu3), (PPh3)(py); n = 1, (X)(Y) = (PPh3)(N3), (PPh3)(TsO) (TsO = tosylate anion)] from [RuIII(salen)(PPh3)(Cl)] is described. These ruthenium(III) complexes are dark green air-stable solids. Their cyclic voltammograms display reversible Ru(IV)/Ru(III) and Ru(III)/Ru(II) couples with E° ranging from 0.37 to 0.76 V and -0.47 to -1.06 V vs Ag/AgNO3 (0.1 M), respectively. At room temperature, they catalyze oxidation of alkenes by PhIO. With norbornene and cyclooctene, epoxides are formed. For arenes, oxidative cleavage of C=C bond is the major reaction pathway. The mechanism of the catalytic oxidation is discussed. © 1989 American Chemical Society.
