合成了一种疏水性钴催化剂，并证明了该催化剂在烃类溶剂辅助下，以氧气为末端氧化剂的醇氧化反应中的有效性。采用一系列具有不同水接触角的催化剂来考察疏水效应。通过反应动力学、同位素效应等对反应过程进行了深入的研究，结果表明，烃类溶剂参与了醇的氧化反应，在原位生成的自由基的帮助下，α-C-H键被顺利活化，醇转化为羰基化合物。疏水效应通过影响溶剂氧化促进了醇的氧化。
A hydrophobic cobalt catalyst was synthesized and proved to be effective in alcohol oxidation under the assistance of hydrocarbon solvent with oxygen as the terminal oxidant. A series of catalysts with different water contact angles was applied to investigate the hydrophobic effect. Further insight into the reaction process was gained by reaction kinetics, isotopic effect, etc. It showed that the hydrocarbon solvent participated in the alcohol oxidation, and with the aid of the in situ generated free radicals, the α‐C−H bond was smoothly activated and the alcohol was converted to carbonyl compounds. The hydrophobic effect promoted the alcohol oxidation by affecting the solvent oxidation.
