Ligands that include Lewis acid/base functionality have extensive applications in bifunctional catalysis using first row metals. In this work, zinc bis(amido), bis(thiolate) and amido-thiolate SNS complexes were prepared and compared as precatalysts for carbonyl hydroboration using pinacolborane. Mechanistic studies revealed two different ligand-assisted precatalyst activation pathways, both leading to an active and robust zinc alkoxide catalyst. This work furthers our understanding of metal-ligand cooperation in first-row metal catalysis.
A zinc complex uses its aryloxide ( vs. amido) donor to generate a Zn–H catalyst that effects quantitative, solvent-free hydroboration of nitriles to the corresponding diborylamines at 1 mol% catalyst loading.
