A new class of palladium catalysts, based on heterocyclicdiphosphines, was rationally designed and synthesized. Application of one of these catalysts allows novel Markovnikov‐selective carbonylation of non‐activated alkynes with heteroarenes to give the corresponding branched α,β‐unsaturated ketones in excellent yields (up to 97 %) and regioselectivities (b/l up to 99:1). In addition to heteroarenes
