Tuning the regioselectivity of the Pd-catalyzed isomerization of methylenecyclopropylcarbinols in acetic acid is achieved by a subtle choice of the ligand and/or solvent. When dioxane is used as the solvent, penta-2,4-dien-1-ols are formed, whereas when AsPh 3 is used as the ligand and toluene is used as the solvent, pent-4-enals are formed. A plausible reaction mechanism is discussed on the basis
