| 英文摘要 | rapid benzene hydroxylation was achieved using a reaction system that consisted of a vanadium-based catalyst, ascorbic acid, and 2,2,6,6-tetramethylpiperidine-1-oxyl (tempo) with molecular oxygen as the oxidant. the hydroxyl radicals that form by a fenton-type process attack the benzene ring to produce a hydroxycyclohexadienyl radical. the hydroxyl hydrogen is then abstracted quickly in the presence of tempo and phenol forms by the transfer of a hydrogen atom from the benzene ring to oxygen. over the [(ch3)(4)n](4)-pmo11vo40 catalyst the phenol yield reached 8.3% with a selectivity of 95% in 1 h while trace amounts of phenol were obtained in the normal system without tempo. |
