Reaction
of [(IPr)Ni(μ-Cl)]<sub>2</sub> (<b>1-Cl</b>; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene)
with
ClMg{CH(SiMe<sub>3</sub>)<sub>2</sub>}·Et<sub>2</sub>O affords
(IPr)Ni{CH(SiMe<sub>3</sub>)<sub>2</sub>} (<b>2</b>), a two-coordinate
Ni(I) alkyl complex. 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.
