A one-step synthesis of 2,4-dinitrostyrene is described. Based on a Stille coupling, the procedure is more amenable to scale-up than the existing methods that require longer reaction sequences and hazardous nitration processes. This easily polymerizable monomer was isolated using a continuous extraction method. The reaction was extended to the synthesis of two other related vinyl monomers including the previously unknown 1,3-dinitro-4,6-divinylbenzene.
本文介绍了一步合成 2,4-二硝基苯乙烯的方法。与需要较长反应序列和危险的硝化过程的现有方法相比,该方法基于斯蒂尔偶联,更适于规模化生产。这种易于聚合的单体是通过连续萃取法分离出来的。该反应扩展到合成其他两种相关的乙烯基单体,包括以前未知的 1,3-二硝基-4,6-二乙烯基苯。
