✦ Synopsis

Novel [Mn III (amp)(bipy)(Cl)] (1) (H 2 amp: N-(hydroxyphenyl)salicyldimine; bipy: 2,2 -bipyridyl) and [Mn III (app)(bipy)-(Cl)] + (2) (H 2 app: N-(hydroxyphenyl)pyridine-2-carboxaldimine; bipy: 2,2 -bipyridyl) complexes have been synthesized and characterized by physico-chemical methods. Complexes 1 and 2 have been employed as catalysts in the oxidation of both saturated and unsaturated hydrocarbons using tert-butylhydroperoxide (t-BuOOH). A mechanism involving formation of and transfer from a reactive highvalent Mn(V)-oxo species as catalytic intermediate is proposed for the catalytic processes.
