The reaction of methylenecyclopropanes (MCPs) with tetrahydrofuran (THF) proceed smoothly in the presence of AgOC(O)CF3 and electrophilic halogenation reagents to give the corresponding 4-(3-halobut-3-enyloxy)butyl 2,2,2-trifluoroacetate derivatives in moderate yields through dual cleavage of C–C and C–O bonds under mild conditions.
在 AgOC(O)CF3 和亲电卤化试剂的存在下,亚甲基环丙烷 (MCP) 与四氢呋喃 (THF) 的反应顺利进行,得到相应的 2,2,2-三氟乙酸 4-(3-卤代丁-3-烯氧基)丁酯在温和条件下通过 C-C 和 C-O 键的双重裂解获得中等产率的衍生物。
