Abstract

Transition-metal-catalyzed C–H and C–C bond activation procedures have attracted significant interest as environmentally friendly processes for organic synthesis. This account summarizes transition-metal-catalyzed transformations of propargylic amines through C(sp³)–H and C(sp³)–C(sp) activation, including hydrogen transfer, deacetylenative homocoupling, fragment exchange, and redox cross-dehydrogenative coupling (CDC). The generation of iminium intermediates is essential for the current transformations based on propargylic amines.
