Kinetics and linear free energy relationship (LFER) of Wittig reaction of ylides of intermediary stability have been investigated.Evidences are presented which indicate that under such cases the reaction follows a second order rate law, first order in phosphorane and aldehyde respectively, and furthermore that electron withdrawing substituents on both benzaldehyde and benzylidenetriphenylphosphorane impose rate enhancement effect upon the reaction.The mechanism of the reaction is discussed on the basis of the experimental findings
