A perfluorometallacycloheptane complex of nickel bipyridine

Reaction of [(bpy)NiEt2] with 1,6-dibromododecafluorohexane in THE at room temperature led to [(bpy) Ni(eta(2)-C,C-C6F12)] (1) in 13% isolated yield. Compound 1 represents the first example of a perfluorinated metallacycloheptane and a rare example of an isolable metallacycloheptane in general. X-ray diffraction studies confirmed the structure of 1. Key nickel bond distances, in A, are: Ni-C6 1.903(9); Ni-C11.925(10); Ni-Nl 2.004(7); Ni-N2 2.011(8). (C) 2017 Elsevier B.V.
