Abstract

While 1,2-bisbis(pentafluorophenyl)phosphinoethane (dFppe) has been shown to impart unusual electronic properties and reactivity in Pd and Pt complexes, analogous Ni systems have remained unexplored. Leveraging the high lability of Ni(CDT) (CDT = trans,trans,trans-1,5,9-cyclododecatriene), we have synthesized a new Ni(0) complex, Ni(dFppe)2. Herein, we describe its structural and spectroscopic characterization and evaluate air stability, ligand substitution behavior, and reactivity in C─C cross-coupling chemistry.
