A method for cobalt‐catalyzed, aminoquinoline‐ and picolinamide‐directed C(sp2)H bond alkenylation by alkynes was developed. The method shows excellent functional‐group tolerance and both internal and terminal alkynes are competent substrates for the coupling. The reaction employs a Co(OAc)2⋅4 H2O catalyst, Mn(OAc)2 co‐catalyst, and oxygen (from air) as a terminal oxidant. In the air: Excellent functional‐group tolerance is observed in the title reaction, and both internal and terminal alkynes are competent substrates for the coupling. The reaction employs Co(OAc)2⋅4 H2O as the catalyst, Mn(OAc)2 as the co‐catalyst, and oxygen (from air) as the terminal oxidant. Piv=pivalate.
