oxy-1-butene and 4-chloro-1-ethynyl-1,5-dimethyl-5-hexenyl acetate, respectively. In contrast, 3-methyl-2-butenyl derivatives 2d–f and 3-methyl-2-butenoic acid afforded a variety of products such as chlorohydrin, vinyl chloride, and sulfoxide other than ene-type products, suggesting that the functional group of R in 2 affects the reaction cou...
3-氯-2-氯甲基-4-(4-氯苯氧基)-1-丁烯 (1) 通过 1-(4-氯苯氧基)-3-甲基-2-的电氧化双烯型氯化以 72% 的收率制备丁烯。在酸(HCl、H2SO4、H3PO4 等)存在下,在室温下在二氯甲烷和水的两层溶剂系统中进行电解。3-氯-2-甲基-4-(4-氯苯氧基)-1-丁烯或1分别被选择性地制备,分别在4或10 F/mol的电流通过后使用铂箔作为未分割电池中的电极。相关的 3-甲基-2-丁烯基衍生物 2b 和 2c 的类似电解提供了烯型产物,3-氯-2-甲基-4-苄氧基-1-丁烯和 4-氯-1-乙炔基-1,分别为 5-二甲基-5-己烯基乙酸酯。相比之下,
