Artykuł
The efficient carbonylative cyclization of 1,2-diiodobenzene with different primary and secondary amines was performed using a palladium complex with an imidazole ligand, PdCl2(BIM)2, as a catalyst. In reactions performed at 1 atm of CO with primary amines, phthalimides were obtained as the only products with yields of up to 100% in 4 h. An even shorter time, 1 h, was sufficient to obtain the same products employing methyl-2-iodobenzoate as a substrate instead of 1,2-diiodobenzene. In an analogous reaction with secondary amines, 1,2-diiodobenzene was converted to three products, formed in amounts dependent on the reaction conditions. The presence of Pd NPs and soluble palladium intermediates indicated their participation in the catalytic reaction.
