Functionalized arenes and heteroarenes are of outstanding importance as pharmaceuticals, agrochemicals, fine and bulk chemicals. Hence, the development of environmentally benign CÀC coupling reactions of arenes is an important topic of organometallic chemistry and catalysis. Elegant examples of direct CÀH transformations of arenes [1] include the addition of olefins to acetophenones (Murai reaction)[2] and aromatic imines,[3] novel additions of ...
