作者进一步研究二苯胺和亚硫酰氯作用形成1.3.7.9四氯苯駢噻嗪(Ⅱ)的反应此反应至少包含两个过程,即苯駢噻嗪环的形成和苯环的氯化。前曾报导苯駢噻嗪(Ⅵ)及5位氧化物(Ⅴ)均能与SoCl_2作用产生四氯苯駢噻嗪(Ⅱ),
The authors further study the reaction of diphenylamine and thionyl chloride to form 1.3.7.9 tetrachlorobenzenethiazin (II). This reaction involves at least two processes, the formation of benzothiazine rings and the chlorination of benzene rings. It was previously reported that both benzothiazine (Ⅵ) and 5-oxide (Ⅴ) were able to interact with SoCl_2 to produce tetrachlorobenzothiazine (Ⅱ)
