摘要: A simple, mild, and facile carbonylation procedure to synthesise 2-arylbenzoxazole derivatives using dicobalt octacarbonyl [Co2(CO)8] as an in situ carbon monoxide source is described. This method tolerant of a variety functional groups the compounds are obtained in high excellent yields. Moreover, reaction performed one-pot with simple workup procedure. The choice catalytic system well base important order ensure yield chemoselectivity reaction. Both electron-rich electron-deficient aryl bromides worked this
