Palladium-Catalyzed Remote para-C−H Activation of Arenes Assisted by a Recyclable Pyridine-Based Template
2021
Direct para-selective C–H functionalization of arenes remains a daunting challenge and is still significantly restricted to a few scaffolds. Herein, we report an unprecedented pyridine-based para-directing template (DT) assisted, Pd-catalyzed para-C–H alkenylation of three classes of arenes, i.e. phenylpropanoic acids, 2-phenyl benzoic acids and benzyl alcohols, with a series of alkenes including perfluoroalkenes. Notably, the pyridine-based para-DT could be easily synthesized and readily recycled under mild conditions. These results may find application in rapid construction of para-substituted arenes and stimulate the exploration of novel methods for para-C–H functionalization of arenes.
