SYNTHESIS OF DI-MU-OXO MANGANESE(III IV) COMPLEXES AS FUNCTIONAL MODELS OF L-PLANTARUM PSEUDO-CATALASE - INFLUENCE OF ELECTRONIC AND STERICFACTORS - CATALYSIS AND KINETICS OF HYDROGEN-PEROXIDE DISPROPORTIONATION/

Di-mu-oxo dimanganese(III/IV) complexes are efficient catalysts for H2 O2 disproportionation in neutral aqueous medium; the activity can be c orrelated to the electron density on the metal and the accessibility o f the catalytic site.
