From the past decades, tremendous efforts have been directed towards the development of transition metal-catalyzed C-H bond activation reactions, which allows the direct functionalization of generally inert C-H bonds. Among various functional groups, alkenyl group has been extensively applied to C-H bond activation strategy while using terminal/internal alkynes and linear alkenes as surrogates for the alkenyl moiety. Despite their remarkable importance and thus achieved considerable advances, C-H alkenylation reactions still suffer from two major issues; one is that the most of the previous reports on C-H alkenylaton relied on only terminal/linear alkynes and alkenes as coupling partners and another is controlling E/Z selectivity with broader scope of substrates. In this study, we present cobalt(III)-catalyzed (E)-selective C-H alkenylation reaction of (hetero)arenes without any double-alkenylation product. The present catalytic system will be expected to set the stage for step- and atom-economic C-H bond activation of arenes and heteroarenes, thereby providing versatile synthetic route to a variety of alkenyl-substituted (hetero)arenes.
