A PRACTICAL SYNTHESIS OF MYRCENOL BY PALLADIUM COMPLEX-CATALYZED ELIMINATION REACTION
A Palladium complex-catalyzed elimination reaction of allyl amines was studied to establish a practical process for production of myrcenol.The catalytic elimination occurred smoothly with the cationic Pd(II) complexes.Among a variety phosphorous ligands, the tetramethylene and the pentamethylene diphosphine ligands proved to be the best ligand with respects to the catalytic activity and selectivity.
