The relative C-O bond cleavage reaction rates (krel) of eight substituted benzyl phenyl ethers (BPE's) have been measured.These C-O bond cleavage reactions were thermally initiated by 2,3-dichloro-5,6-dicyanoquinone (DDQ).The equilibrium constants (K) for charge-transfer complex formation of these BPE's with the electron acceptors DDQ and TCNE in the solvent methylene chloride have also been determined at room temperature.The best correlation of log krel for DDQ reactions has been observed in these reactions.From this data, hydride transfer to DDQ is the rate-determining step of the reaction.
