Copper(0)-induced deselenative insertion of N,N-disubstituted selenoamides into acetylenic C-H bond leading to propargylamines.
Upon heating at 110 degrees C in the presence of copper(0) powder, terminal acetylenes undergo a novel deselenative C-H bond insertion reaction of N,N-disubstituted selenoamides, affording the corresponding propargylamines in good to excellent yields, selectively.
