A new reagent for the efficient preparation of gem-chloronitroso compounds has been developed. The reaction of ketoximes with N-tert-butyl-N-chlorocyanamide takes place instantaneously in carbon tetrachloride at room temperature with excellent yields under mild conditions.

chlorotrimethylsilane to give nitryl chloride, which is characterized by its UV spectrum. If it is generated in presence of ketoximes, gem-chloronitro as well as gem-chloronitroso compounds are formed in almost equal amounts, which together account for up to 80% yield. This is possibly the simplest one-pot reaction for the preparation of gem-chloronitro compounds which find several synthetic applications
而异戊亚硝酸盐发生反应与氯代三甲基硅烷,得到NOCl,异硝酸戊不会产生NO 2 Cl可硅试剂。但是,硝酸乙酰酯可以与三甲基氯硅烷成功反应,生成硝酰氯,其特征在于其紫外光谱。如果在酮肟的存在而产生,宝石-chloronitro以及宝石-chloronitroso化合物形成在几乎相等的量,合计占高达80%的产率。这可能是制备宝石-氯硝基化合物的最简单的一锅法,该方法发现了几种合成应用。如果NO 2在环烯烃的存在下生成Cl,得到相应的1,2-二氯环烷烃。考虑到现有的证据,提出最初由氯代三甲基硅烷-乙酰硝酸盐反应形成的NO 2 Cl分解为Cl 2和N 2 O 4。然后,氯与肟反应生成第一种宝石-氯亚硝基化合物,然后被NO 2 Cl或N 2 O 4氧化成宝石-氯亚硝基化合物,再与环烯烃一起生成二氯环烷烃。
