A method has been developed for the introduction of nonaromatic heterocyclic structures onto aryl and heteroaryl bromides using alkyl tosylates in a reductive cross-coupling manifold. This protocol offers an improvement over previous methods by utilizing alkyl tosylate coupling partners that are bench-stable, crystalline solids that can be prepared from inexpensive, commercially available alcohols.

Reductive cross-coupling allows the directC–Cbond formation between two organic halideswithout the need for preformation of an organometallic reagent. A method has been developed for the reductive cross-coupling of nonaromatic, heterocyclic bromides with aryl or heteroaryl bromides. The developed conditions use an air-stable Ni(II) source in the presence of a diamine ligand and a metal reductant
