TL;DR: The Sonogashira coupling reaction of aryl bromides with a variety of terminal alkynes in DMSO at 125 °C gave internal arylated alkynes using low-loaded Pd(acac) 2 with hydrazone as a ligand and CuI as the co-catalyst in good yields.

TL;DR: TEMPO-mediated reactions of alkenyl hydrazones afforded azaheterocycles via sp(3) C-H allylic amination feature a sequence of remote allylic H-radical shift and allylic homolytic substitution with hydrazone radicals.
Abstract: TEMPO-mediated reactions of alkenyl hydrazones afforded azaheterocycles via sp3 C–H allylic amination. The transformation is featured by a sequence of remote allylic H-radical shift and allylic homolytic substitution with hydrazone radicals.
