The first chromium-catalyzed regioselective addition of para-C-H bonds, of pyridines across styrenes is disclosed. The hydrofunctionalization reaction was promoted by a low-cost chromium(III) chloride combining with a cyclohexyl Grignard reagent and 2,2'-bipyridine, which allows for the highly selective formation of branched products via the cleavage of inert C-H bonds Of pyridines.
