A novel Pd-catalyzed assembly of N-phenylphthalimide by merging of [4+1] cycloaddition and difluorocarbene transfer carbonylation from 2-iodo-N-phenylbenzamides and difluorocarbene precursors is disclosed. In this reaction, difluorocarbene acts as a carbonyl source and simultaneously forms one C-C bond, one C-N bond and one C=O bond to produce N-phenylphthalimides in high yields.
