title: Ni(II)-catalyzed dehydrative alkynylation of unactivated (hetero)aryl C-H bonds using oxygen: a user-friendly approach.
abstract: Ni(II)-catalyzed dehydrative alkynylation of unactivated C(sp(2))-H bonds with terminal alkynes under atmospheric pressure of oxygen was developped. This reaction features the use of catalytic amounts of nickel as the catalyst and O2 as the sole oxidant, providing a user-friendly approach to the synthesis of aryl alkynes.
