以乙酸钴和溴苄为催化剂,考察了三乙胺、2,6-二甲基吡啶、吡啶、4-羧基吡啶和4-N,N-二甲氨基吡啶等不同含氮有机化合物对甲苯氧化反应的影响.结果发现4-N,N-二甲氨基吡啶表现出促进效应,并探讨了其促进机制.
The influence of different nitrous organic compounds, including triethylamine, 2,6-dimethylpyridine, 4-carboxylic pyridine, pyridine, and 4-N,N-dimethylamino pyridine (DMAP), on the oxidation of toluene catalyzed by cobalt acetate and benzyl bromide was investigated. DMAP showed improvement for the activity. The promoting effect was discussed.
