An Efficient synthesis of Weinreb amides and ketones via palladium nanoparticles on ZIF-8 catalysed carbonylative coupling†
Abstract
Heterogeneously catalysed carbonylative coupling reactions such as aminocarbonylation and Suzuki-carbonylation are reported using Pd nanoparticles supported on ZIF-8 for efficient and environmentally attractive synthesis of Weinreb amides and ketones from aryl bromides or iodides. The catalyst is air stable, offers high activity with very low palladium leaching and is recyclable. The presence of a phosphine ligand was required when aryl bromides were used as substrates, while no ligand was necessary when aryl iodides were used.
