Novel cobalt-based heterogeneous catalysts have been developed for the direct oxidative esterification of alcohols using molecular oxygen as benign oxidant. Pyrolysis of nitrogen-ligated cobalt(II) acetate supported on commercial carbon transforms typical homogeneous complexes to highly active and selective heterogeneous Co3O4-N@C materials. By applying these catalysts in the presence of oxygen, the cross and self-esterification of alcohols to esters proceeds in good to excellent yields.
新型钴基多相催化剂已被开发出来，用于以分子氧为温和氧化剂的醇的直接氧化酯化。氮配位的醋酸钴负载在商业碳上的热解将典型的均相配合物转化为高活性和选择性的 Co3O4-N@C 多相材料。通过在氧气存在下使用这些催化剂，醇的交叉和自身酯化反应以良好至优异的收率进行。
