Ortho C–H arylation of arenes at room temperature using visible light ruthenium C–H activation†
Abstract
A ruthenium-catalyzed ortho C–H arylation process is described using visible light. Using the readily available catalyst [RuCl2(p-cymene)]2, visible light irradiation was found to enable arylation of 2-aryl-pyridines at room temperature for a range of aryl bromides and iodides.
