Polystyrene‐supported palladium (Pd@PS) nanoparticles (NPs) have been used to catalyze the aminocarbonylation of arylhalides with amines using oxalic acid as a CO source for the first‐time for the synthesis of amides. Furthermore, o‐iodoacetophenones participated in amidation and cyclization reactions to give isoindolinones in a single step following a concerted approach. Oxalic acid has been used
The metal‐freeselective and diversesynthesis of threedistinctsets of isoindolinonesfrom2‐alkynylbenzoicacids and amines in a controlled manner is reported. This process features metalfree, readily available starting materials, broad substrate scope, excellent selectivity, good to high yields, good functional group tolerance, simple operation, high bond‐forming efficiency, and step economy.
