The oxidative coupling reaction of 2,6dimethylphenol (DMP) with H 2 O 2 catalyzed by four copper(II) complexes was investigated in Tris-HNO 3 buffer solution at 25 C. The kinetics of formation of diphenoquinone (DPQ, 4-(3,5-dimethyl-4-oxo-2,5-cyclohexadienylidene)-2,6-dimethyl-2,5-cyclohexadienone)
The oxidative coupling polymerization of 2,6-dimethylphenol (DMP) catalysed by copper(II) complexes of N-methylimidazole in toluene/iso-propanol (13/2v/v) or 1,2-dichlorobenzene/methanol (ODCB/MeOH) (13/2 v/v) was investigated. EPR spectra of these complexes indicated that the complex had a mononucl
## Abstract Polyphenylene oxide (PPO) was prepared via oxidative coupling polymerization of 2,6βdimethylphenol (DMP) catalyzed by copper salt. The ligand was a novel series of random copolymers (PSVP) of styrene and 4βvinylpyridine prepared by reversible additionβfragmentation chain transfer (RAFT)
