Potassium hydroxide, in presence of tetraethyleneglycol dimethyl ether, easily abstracts hydrogen chloride or hydrogen bromide from secondary and tertiary halides, but primary chlorides lead to roughly equal amounts of elimination and substitution products. Addition of small quantities of trimethylamine, however, starts a catalytic cycle involving ammonium salts and favoring alkene formation. The described
在四乙二醇二甲醚存在下,氢氧化钾很容易从仲和叔卤化物中提取氯化氢或溴化氢,但伯氯化物导致消除和取代产物的量大致相等。然而,添加少量的三甲胺开始了涉及铵盐并有利于烯烃形成的催化循环。所描述的方法似乎比任何其他非热解方法更有效,更经济。
