Treatment of cycliccarbonate of 3-alkene-1,2-diols or 4-methylcarbonate of 2-alkene-1,4-diols with a catalytic amount of Pd(PPh3)4 in aqueous THF or AcOH gave α,β-unsaturatedaldehydes in good yields. The reaction can be interpreted by the regioselective 1,4-hydrogen migration of π-allylpalladium intermediate.
