The first example of the oxidative addition of a C(sp3)–F bond in trifluoromethylarenes to a nickel(0) complex is described. A nickel(0) complex that bears two N-heterocyclic carbene (NHC) ligands of low steric demand is able to cleave C(sp3)–F bonds of trifluoromethylarenes to afford the corres...

Ni(0)-Catalyzed Synthesis of Polycyclic α,β-Unsaturated γ-Lactams via Intramolecular Carbonylative Cycloaddition of Yne-imines with CO

Synlett, 2020, eFirst Article
A Ni(0)-catalyzed intramolecular carbonylative cycloaddition between 1,5-yne-imines and carbon monoxide (CO) is disclosed. When Ni(CO)3PCy3 was employed as a pre-catalyst, a variety of polycyclic α,β-unsaturated γ-lactams were prepared in up to 78% yield with 100% atom efficiency. Aza-nickelacycles, generated by the oxidative cyclization of yne-imines on the Ni(0) center, were experimentally confirmed as key intermediates. Moreover, diastereoselective transformations of the obtained products to afford highly substituted polycyclic γ-lactams with three contiguous carbon stereocenters are reported.

Trifluorovinylzinc is a common synthetic intermediate for trifluorovinyl derivatives, including α,β,β-trifluorostyrenes and hexafluorobutadiene. Here, we report a novel synthetic approach for the formation of trifluorovinylzinc chloride via a C–F bond activation of tetrafluoroethylene (TFE), wh...
