全氯甲硫醇

化合物

全氯甲硫醇是化学式 CCl3SCl的有机硫化合物,主要用于合成染料和抗真菌剂盖普丹灭菌丹英语folpet。它是无色且难闻刺鼻的油状液体,不过商购的样本呈黄色。它不溶于水,可溶于有机溶剂。全氯甲硫醇其实是一种硫基氯英语sulfenyl chloride,不是硫醇[6]

历史

1915年,法国在香槟战役中把全氯甲硫醇用作化学武器,但很快就因为容易被发现、分解和去除而被淘汰。[7]

制备

全氯甲硫醇是由Rathke于1873年[6]通过氯气和二硫化碳反应发现的,此方法至今仍用于生产全氯甲硫醇。这个反应由[8]氯化氢催化。[9]

CS2 + 3 Cl2 → CCl3SCl + SCl2
2 CS2 + 5 Cl2 → 2 CCl3SCl + S2Cl2

它也可以由氯化二甲硫醚[10]硫光气[11][12]而成。

反应

全氯甲硫醇会缓慢水解:[13]

CSCl4 + 2 H2O → CO2 + 4 HCl + 18 S8

它会被硝酸氧化,生成三氯甲磺酰氯(Cl3CSO2Cl),这是一种白色固体。[7]它在140 °C的二甲苯三氯化铁催化下用[14]9,10-二氢蒽[15]脱氯,可以合成硫光气[16]

 

全氯甲硫醇会和氟化汞氟化银发生卤素交换反应,生成二氯氟甲硫基氯(CCl2FSCl)[17][18],后者可用来合成抗真菌剂苯氟磺胺德语Dichlofluanid对甲抑菌灵德语Tolylfluanid

危险性

全氯甲硫醇可通过呼吸道、皮肤或口服吸收。它会刺激眼睛、喉咙、支气管和肺泡,也会导致肝脏和肾脏损伤。[19]对大鼠[20][21]和小鼠[22][23]的动物实验表明全氯甲硫醇是剧毒,中毒症状有腹泻、皮肤刺激以及呼吸急促。[24]
