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)butyl2,2,2-trifluoroacetatederivatives in moderate yields through dualcleavage of C–C and C–Obonds under mild conditions.
