hitherto unknown isomeric fluoronitrobenzenesulfonyl chlorides is described. The compounds are prepared from difluoronitrobenzenes by a two-step procedure. In the first step the starting compounds undergo a regioselective reaction with phenylmethanethiol giving rise to the corresponding thioethers. The oxidative cleavage of the latter with chlorine results in the sulfonyl chlorides in good yields. One
描述了五个迄今未知的异构体氟硝基苯磺酰氯的合成。该化合物由二氟硝基苯通过两步程序制备。在第一步中,起始化合物与苯基甲硫醇进行区域选择性反应,生成相应的硫醚。后者用氯气的氧化裂解导致磺酰氯的收率很高。提供了2-氟-6-硝基苯磺酰氯的三重顺序官能化的一个实例,其显示了标题化合物的合成效用。
