Transition-metal-free multicomponent reactions involving arynes, isocyanides, and CO2 as the third component resulted in the formation of N-substituted phthalimides in good yields, whereas the use of water as the third component furnished benzamide derivatives in good yields. These reactions took place under mild conditions with broad scope.
