[chemical reaction: see text]. We report herein the first examples of the addition of aryl- and alkenylboronic acids catalyzed by RhI complexes to 2,4-dienoate esters. Three different types of products have been obtained depending on the substitution pattern of the starting ester and the organoboronic acid: 1,6-conjugate addition products, 1,4-conjugate addition products, and Heck reaction products
