  alcohols catalyzed by mesoporous metal oxides (manganese and cobalt oxides) is reported under base and solvent free conditions. For a range of aliphatic alcohols, up to 90 % conversions to esters was achieved. The catalytic reaction is likewise applicable to neat aldehydes as substrates with yields of up to 86 %. High pressure batch reaction for ethanol to ethyl acetate led to 22 % yield. Isotope labeling

  据报道，在无碱和无溶剂条件下，介孔金属氧化物（锰和钴的氧化物）催化的伯醇有氧自酯化反应。对于一系列脂族醇，可实现高达90％的酯转化率。催化反应同样适用于纯醛作为底物，产率最高为86％。乙醇至乙酸乙酯的高压间歇反应导致22％的收率。同位素标记研究表明催化剂表面发生脱羧。力学和动力学实验将氧回弹和α-碳去除作为中间步骤。与中孔氧化锰相比，中孔氧化钴显示出约高20％的催化活性。
