将2-巯基-△2-噻唑啉(Ⅰ,R=H)(即四氢噻唑-2-硫酮)和环氧乙烷在二氧六环溶液中作用,希望得到2-β-羟乙基硫化-△2-噻唑啉(Ⅱ,R=H)。但实际生成四氢噻唑-2-酮(Ⅲ,R=H)和环硫乙烷,与按Crawhall等方法制得的样品,各种物理性质完全相同,混合熔点不降。改将2-巯基-△2-噻唑啉在碱性溶液中与氯乙醇反应,仍然得到四氢噻唑-2-酮。

The titled reactions were observed when thiazolidine-2-thione and 5-methyl-thiazolidine-2-thione were treated respectively with ethylene oxide.A simple reaction mechanism was proposed.
