An unprecedented catalyst-controlled regiodivergent strategy has been developed that allows efficient access to structurally diverse 1,3-dienyl and allyl esters from common propargyl esters with high regio- and stereochemical outcomes. The ligand backbone is crucial for the regioselectivity pattern, enabling the palladium catalyst to involve electrophilic metal catalysis or sequential oxidative addition–reductive
