through direct coupling of C(sp3)-H bonds with unsaturated hydrocarbons represents an atom-economical and redox-neutral way for functionalizing chemically inert positions, such as those β to a carbonyl group. While most existing β-functionalization methods utilize a directing group (DG) strategy, here we report a Pd-catalyzed intramolecular β-alkenylation of ketones using alkynes as the coupling partner without
