In the presence of a Ni catalyst and Zn, various aryl and vinyl bromides are reductively coupled with alkyl bromides in high yields. Under similar conditions, activated aryl chlorides can also be coupled with bromoalkanes. The protocols are highly functional-group tolerant, and the reactions are assembled on the benchtop with no special precautions to exclude air or moisture.
