Fujita, Takeshi published the artcileCatalytic defluorinative [3 + 2] cycloaddition of trifluoromethylalkenes with alkynes via reduction of nickel(II) fluoride species, Name: 7-Bromohept-1-yne, the publication is Dalton Transactions (2015), 44(45), 19460-19463, database is CAplus and MEDLINE.
Nickel-catalyzed [3+2] cycloaddition of 2-trifluoromethyl-1-alkenes with alkynes via domino C-F bond activation was achieved by sequential β-fluorine elimination to give corresponding cyclopentadienes I [R1 = C6H5, 3-FC6H4, t-BuOC(O), etc.; R2 = n-Pr, iPr; R3 = Me, n-Pr] regioselectively. The nickel(II) fluoride species formed in this reaction was reduced by a diboron compound, regenerating the catalytically active nickel(0) species.
