报道了以酸性多级孔ZSM-5沸石为催化剂,以二苯甲醇和对甲基苯磺酰胺为原料,实现磺酰胺的N-烷基化反应制备N-取代的酰胺化合物,同时进行反应条件的筛选(溶剂,温度,催化剂的量),最终确定该反应的最优条件。研究发现,以1,2-二氯乙烷为溶剂,80oC下N2氛围下,反应6 h获得最高的产物收率。
Reported acid multi-level pore ZSM-5 zeolite as a catalyst, benzhydrol and p-methylbenzenesulfonamide as raw materials, the sulfonamide N-alkylation reaction to prepare N-substituted amide compounds, while the reaction conditions Screening (solvent, temperature, amount of catalyst) finally determines the optimal conditions for the reaction. The study found that 1,2-dichloroethane as solvent, 80oC under N2 atmosphere, the reaction for 6 h to obtain the highest yield.
