Abstract

A novel microwave-promoted protocol mediated by Mn(OAc)3 was developed for the single-electron-transfer oxidative direct C-H bond arylation of (hetero)arenes with aryl and hetero-arylboronic acids. Various electron-deactivated and electron-rich heteroarenes and benzene underwent successfully the direct arylation in this general process. The use of slight excess of heteroarene or benzene in this method was found to be sufficient.
