Cobalt-catalyzed, aminoquinoline-directed C(sp²)-H bond alkenylation by alkynes.


ABSTRACT: A method for cobalt-catalyzed, aminoquinoline- and picolinamide-directed C(sp(2))-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.
