Reactions of 4,5-dihydrooxazol-5-one derivatives with 4-methylbenzene-1,2-dithiol in the presence of triethylamine includes nucleophilic attack by the thiol group on the carbonyl carbon atom in the oxazole ring, followed by opening of the latter and recyclization to 1,4-benzodithiine derivatives.
在三乙胺存在下,4,5-二氢噁唑-5-酮衍生物与4-甲基苯-1,2-二硫酚的反应涉及硫醇基团对噁唑环中的羰基碳原子的亲核攻击,随后噁唑环的打开并重新环合,形成1,4-苯并二硫因衍生物。
