The oxidation of phenolic substrates with H2O2 catalysed by MnIV2(mu-O)3(TMTACN)22 1, (TMTACN, 1,4,7-trimethyl-1,4,7-triazacyclononane) has been investigated by use of ESI mass spectrometry. The role of the phenols as one-electron reductants and as co-ligands in the stabilisation and reaction of an intermediate O=MnV species has been analysed and the presence of a variety of manganese species in solution has been explained. Our results lead to a proposed mechanism for the catalytic oxidation of phenols in this system.
利用电喷雾质谱法研究了由MnIV2(μ-O)3(TMTACN)22 1（TMTACN，1,4,7-三甲基-1,4,7-三氮杂环壬烷）催化H2O2氧化酚类底物的反应。分析了酚类作为单电子还原剂以及作为中间体O=MnV物种稳定化和反应中的共配体的作用，并解释了溶液中各种锰物种的存在情况。我们的结果提出了该体系中酚类催化氧化的机理。
