chlorides are obtained by the action of sulphur monochloride on a primary aromatic amine, its salts, or N-acyl derivatives. Four reactions are involved, (i) the formation of the heterocyclic ring, (ii) the chlorination of the aromatic ring, (iii) replacement of electron-attracting groups in the ortho- and para-positions by chlorine, and (iv) the oxidation of the sulphur atom in position 2. A likely
通过一氯化硫对伯芳族胺,其盐或N-酰基衍生物的作用获得1,3,2-苄硫唑硫鎓氯化物。涉及四个反应,(i)杂环的形成,(ii)芳环的氯化,(iii)用氯取代邻位和对位的吸引电子的基团,和(iv) 2位硫原子的氧化。考虑了可能的反应顺序,并提供了支持每个阶段的实验证据。
