Abstract:A manganese(III) corrole complex, 1, has been synthesized and used to study a potential mechanism for oxidation of water to molecular oxygen. Oxidation by t-BuOOH gave the Mn-V=O complex 2. Addition of hydroxide Led to release of oxygen via the Mn-IV complex 4 and regeneration of complex 1. It could be shown that the oxygen from O-18-labeted water was incorporated in both the formed molecular oxygen and the peroxy intermediate 4.

Pre One:Formation of a new hybrid complex via coordination interaction between 5,10,15-tritolyl-20-(4-and 3-pyridyl)porphyrin or 5,10,15-triphenyl-20-(4-pyridyl)porphyrin and the alpha-[MSiW11O39](6-) Keggin-type polyoxometalate (M = Co2+ and Ni2+)

Next One:Synthesis of unnatural lamellerin o derivatives
