While 1,2-bis[bis(pentafluorophenyl)phosphino]ethane (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.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

SN2 Reaction: Transition State
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...
