Zr(OH)4 can catalyze the selective oxidation of anilines to azoxybenzenes, symmetric/unsymmetric azobenzenes and nitrosobenzenes for a wide range of substrates. Control experiments and DFT calculations reveal that the activation of H2O2 and O2 can be attributed to the bridging hydroxyl and terminal hydroxyl groups of Zr(OH)4, respectively.
Zr(OH) 4可以催化苯胺选择性氧化为偶氮苯、对称/不对称偶氮苯和亚硝基苯,适用于多种底物。对照实验和 DFT 计算表明,H 2 O 2和 O 2的活化可分别归因于 Zr(OH) 4的桥接羟基和末端羟基。
