1,4,2-dithiazolidine or 1,3-thiazetidine heterocycles was developed by reactions of phenylthioureas with 1,1-dichloro-2-nitroethene. The solvent has a significant influence on the type of product formation. 1,4,2-Dithiazolidines were formed in the aprotic solvent chloroform, while in the protic solvent ethanol, 1,3-thiazetidines were the main products.
通过苯硫脲与1,1-二氯-2-硝基乙烯的反应,开发了一种制备1,4,2-二噻唑烷或1,3-噻氮杂环丁烷杂环的方法。溶剂对产物形成的类型有重大影响。在质子惰性溶剂氯仿中形成1,4,2-二噻唑烷,而在质子惰性溶剂乙醇中,主要产物为1,3-噻唑烷。
