A microwave-assisted method for the synthesis of polynitrostilbenes involving the condensation of 2,4,6-trinitro-m-xylene and 2,4,6-trinitrotoluene with aryl aldehydes in the presence of piperidine and silica-gel is reported. Compared with conventional methods, a shorter reaction time is required and this method has a lower environmental impact. A mechanism for the reaction is also proposed and supported
报道了一种微波辅助合成聚硝基二甲苯的方法,包括在哌啶和硅胶存在下将 2,4,6-三硝基间二甲苯和 2,4,6-三硝基甲苯与芳基醛缩合。与传统方法相比,该方法所需的反应时间更短,对环境的影响更小。紫外-可见吸收光谱也提出并支持了该反应的机制。
