Article Synopsis
- Several manganese(I) complexes with chelating ligands that incorporate imidazol-2-ylidene (ImNHC) and 1,2,3-triazol-5-ylidene (tzNHC) were successfully synthesized and characterized.
- The ImNHC-tzNHC ligands were found to have stronger electron donation abilities compared to another ligand configuration (ImNHC-Ntz) and demonstrated effectiveness as non-bifunctional catalysts for α-alkylation of nitriles using alcohols.
- Notably, the catalyst with a weaker triazole-N donor showed higher catalytic activity, yielding a variety of successful coupling products with high efficiency while operating via a Borrowing Hydrogen mechanism.
A facile process for the catalyst-free and solvent-free hydroboration of aromatic as well as heteroaromatic imines is reported. This atom-economic methodology is scalable, compatible with sterically and electronically diverse imines, displaying excellent tolerance towards various functional groups, and works efficiently at ambient temperature in most of the cases, affording secondary amines in good to excellent yield after hydrolysis.
