Synthesis of benzoxazoles an iron-catalyzed domino C-N/C-O cross-coupling reaction.

An eco-friendly and efficient method has been developed for the synthesis of 2-arylbenzoxazoles a domino iron-catalyzed C-N/C-O cross-coupling reaction. Some of the issues typically encountered during the synthesis of 2-arylbenzoxazoles in the presence of palladium and copper catalysts, including poor substrate scope and long reaction times have been addressed using this newly developed iron-catalyzed method.
