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 (18)O-labeled water was incorporated in both the formed molecular oxygen and the peroxy intermediate 4.
一种锰(III)卟吩配合物1已被合成,并用于研究水氧化为分子氧的潜在机制。叔丁基过氧化氢氧化得到锰(V)=O配合物2。加入氢氧根会通过锰(IV)配合物4释放氧气,并使配合物1再生。可以证明,来自(18)O标记水的氧既掺入了生成的分子氧中,也掺入了过氧中间体4中。
