application of palladium on carbon (Pd/C) as a heterogeneous recyclable catalyst was investigated for the double carbonylation of o-dihaloarenes with amines providing excellent yield of N-substituted phthalimides in shorter reaction time as compared to earlier reported homogeneous protocols. Furthermore, the scope of the developed protocol was applied for the synthesis N-substituted phthalimides from o-halobenzoates

The palladium-catalyzed aminocarbonylation of o-halobenzoates produces 2-substituted isoindole-1,3-diones in good yields. This methodology provides a good one-step approach to this important class of heterocycles and tolerates a variety of functional groups, including methoxy, alcohol, ketone, and nitro groups.
Carbonylative Cyclization of o-Halobenzoic Acids for Synthesis of N-Substituted Phthalimides Using Polymer-Supported Palladium-N-Heterocyclic Carbene as an Efficient, Heterogeneous, and Reusable Catalyst
Abstract The carbonylative cyclization of o-iodobenzoic acid with a variety of primary amines and carbon monoxide (1 bar) using a polymer-supported palladium–N-heterocycliccarbenecomplex (PS-Pd-NHC) as the catalyst gives N-substituted 1H-isoindole-1,3(2H)-diones (phthalimides) in good to excellent yields with a short reaction time. The catalyst is efficient, heterogeneous, and phosphine-free, it
