Hexachlorobutadiene reacts with MeONa in refluxing methanol to give (Z)-4,4-dimethoxy2-oxobut-3-enoic acid and 2,4,4-trichloro-1,1,1,3-tetramethoxybut-2-ene, which were converted to methyl (Z)-4,4-dimethoxy-2-oxobut-3-enoate and methyl (Z)-2,4,4-trichloro-3methoxybut-2-enoate upon treatment with CH2N2 and acid hydrolysis, respectively.
六氯丁二烯在回流甲醇中与 MeONa 反应生成 (Z)-4,4-二甲氧基2-氧代丁-3-烯酸和 2,4,4-三氯-1,1,1,3-四甲氧基丁-2-烯。在用 CH2N2 处理和酸水解后,分别转化为 (Z)-4,4-二甲氧基-2-氧代丁-3-烯酸甲酯和 (Z)-2,4,4-三氯-3甲氧基丁-2-烯酸甲酯。
