The reaction of a manganese(V)-oxo porphyrinoid complex with the Lewis acid B(C6F5)3 leads to reversible stabilization of the valence tautomer Mn(IV)(O)(π-radical cation). The latter complex, in combination with B(C6F5)3, reacts with ArO-H substrates via formal hydrogen-atom transfer and exhibits dramatically increased reaction rates over the Mn(V)(O) starting material.
一种锰（V）-氧代卟啉类配合物与路易斯酸B(C6F5)3反应，可使价互变异构体Mn(IV)(O)(π-自由基阳离子)可逆稳定。后一种配合物与B(C6F5)3结合，通过形式上的氢原子转移与ArO-H底物反应，与起始原料Mn(V)(O)相比，反应速率显著提高。
