A nickel-catalyzed reductive coupling between acid fluorides and vinyl triflates has been described. This method provides an efficient access to various enones and avoids the requirement for acyl or vinyl metallic reagents in the conventional approaches. The reaction proceeds with a broad range of acid fluorides and cyclic vinyl triflates, tolerating several functional groups. The utility of this synthetic

carbonyl compounds and diethyl diazomethylphosphonate, can be efficiently trapped by alkenes to give alkylidene-cyclopropane adducts which undergo either [1,3] allylseleniderearrangement or oxidative selenoxide [2,3] sigmatropic rearrangement to produce 1-phenylseleno- or 1-hydroxy-1-vinylcyclopropanes respectively.
