Described are several classes of Ni(0) mediated cyanative alkeneâaldehyde coupling reactions, providing 6-membered cores, which complement existing cyclization technology in several respects. Et2AlCN was used as both a cyclization accelerator and CN source. The NHC ligand may have a positive effect in differentiating reductive elimination and syn-β-hydride elimination.
