pyridinium salts were synthesized and employed as metal-free catalyst for the selectiveoxidation of methyl aromatic hydrocarbon with molecular oxygen. The electronic effect of the substitutes was found to be an important factor for the catalytic performance. With the introduction of electron-donating substitute –N(CH3)2, the conversion of p-xylene and selectivity of p-toluic acid could be simultaneously increased
合成了一系列N-烷基吡啶鎓盐,并将其用作无金属催化剂,用于分子氧选择性氧化甲基芳烃。发现替代物的电子效应是催化性能的重要因素。通过引入给电子取代物-N(CH 3 ) 2 ,可以同时提高对二甲苯的转化率和对甲苯甲酸的选择性。1-Benzyl-4- N , N-二甲基氨基吡啶鎓盐的催化活性最高,选择性氧化对甲苯甲酸的转化率为95%,选择性为84% 。对二甲苯。在没有任何金属物质的情况下,几种甲基芳烃都可以用所报道的催化剂有效地氧化。
