An analogous two-coordinate aryl derivative, (IPr)­Ni­(dmp) (dmp = 2,6-dimesitylphenyl), can be similarly prepared from Li­(dmp) and <b>1-Cl</b>. Reaction of <b>2</b> with alkyl bromides gives the three-coordinate Ni­(II) alkyl halide complex (IPr)­Ni­{CH­(SiMe<sub>3</sub>)<sub>2</sub>}­Br. Evidence for a radical mechanism is presented to explain the reaction of <b>2</b> with alkyl halides.
