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

sterically hindered alcohols has been successfully developed via radical–radical coupling reactions enabled by mild and redox-neutral photocatalysis. With alkylsilicates as the radical precursors, a range of primaryalkylradicals bearing various functional groups could couple with a range of phthalimides and activated ketones.
