Without using any transitionmetal and base, an eco-friendly, practical and economical protocol has been established for the one-pot synthesis of diverse (E)-1-phenyl-4-sulfonylbut-1-enes from easily accessible starting materials. This strategy features a wide substrate scope, tolerates a broad range of functional groups, employs a less expensive oxidant, is operationally simple, and can be easily scaled-up.

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. Novel 4-(3-halobut-3-enyloxy)butyl 2,2,2-trifluoroacetate derivatives can be synthesized by AgI-mediated reactions of arylmethylenecyclopropanes with tetrahydrofuran at room temperature through dual cleavage of C-C and C-O bonds.
