The combination of palladium catalysis and iridium photocatalysis enables a general catalytic anti-hydroarylation of electron-deficient internal alkynes with a broad range of arylboronic acids. The reaction of ortho-substituted boronic acids provides pharmaceutically relevant heterocyclic cores via a cascade process.
