Reaction of 2-chlorovinyldichloroarsine (Lewisite-1) with alcohols, thiols, diols, and hydroxy thiols in water at 40°C has been examined. The expected derivatization products, dialkyl 2-chlorovinylarsonites or corresponding arsonodithiolites, were obtained with alcohols and thiols, whereas reactions with bifunctional diols and hydroxythiols produced analogous cyclic esters. All derivatives may be easily
研究了 2-氯乙烯基二氯胂(Lewisite-1)与醇、硫醇、二醇和羟基硫醇在 40°C 下在水中的反应。用醇和硫醇获得预期的衍生产物,二烷基 2-氯乙烯基亚拉森酯或相应的 arsonodithiolites,而与双官能二醇和羟基硫醇的反应产生类似的环酯。使用气相色谱法可以很容易地检测所有衍生物。发现该反应可用于将双(2-羟乙基)硫化物(硫二甘醇)(一种硫芥子分解产物)轻松转化为稳定的八元环状亚砷酸盐衍生物。用二氯甲烷萃取后,可以使用 GC/MS 轻松且选择性地检测水基质中 100 ppb 硫代二甘醇含量的衍生物,从而避免繁琐的水蒸发和硅烷化过程。
