通过活化吡啶盐的硝基衍生物,可以选择性的高产率的生成邻-硝基苯酚.例如将NO_2-N_2O_4的混合物通入N-癸基吡啶烟酸盐,生成的酰基硝酸盐和苯
The o-nitrophenol can be selectively and efficiently produced by activating the nitro derivative of the pyridinium salt, for example, passing a mixture of NO 2 -N 2 O 4 into N-decyl pyridine nicotinate, the resulting acyl nitrate and benzene
