The Michael addition reactions of Z and E 4-methyl-benzaldoximes with propene were investigated theoretically by DFT method at B3LYP/6-31G* level.The calculation results show that both addition reactions are concerted processes accompanied by the migration of hydrogen from the atom oxygen to carbon.Both products Z and E nitrones have dipolar charge distributions and activities.Z isomer is more favorable in the reaction due to the barrier is lower.
