In a Pd-catalyzed formation of arylnitromethanes from readily available aryl halides or triflates, 2-10 equiv of nitromethane in dioxane as solvent can be employed in comparison to prior work that used nitromethane as solvent (185 equiv). The present transformation reduces the hazards associated with MeNO2, provides high yields at relatively low temperatures, and tolerates an array of functionality.
