The Pd-catalyzed Suzuki–Miyaura coupling reaction of unsymmetric 1,3-disubstituted secondary allylic carbonates with arylboronicacids has been developed in a wet solvent under a base-free system to afford allyl–aryl coupling products in a high level of isolated yields with complete regio- and E/Z-selectivities with good to excellent chemoselectivities. The coupling reaction of optically active allyl
