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.

Pd催化[4+1]环加成反应合成N-取代邻苯二甲酰亚胺


公开了一种新颖的 Pd 催化的 N-苯基邻苯二甲酰亚胺组装方法，通过合并 [4+1] 环加成和来自 2-碘-N-苯基苯甲酰胺和二氟卡宾前体的二氟卡宾转移羰基化。在此反应中，二氟卡宾作为羰基源，同时形成1个CC键、1个CN键和1个C=O键，以高产率生成N-苯基邻苯二甲酰亚胺。
