摘要
在醋酸钯［Ｐｄ（ＯＡｃ）_２］／氢醌（ＨＱ）／酞菁铁（ＦｅＰｃ）催化环己烯氧化合成环己酮反应中，应用ＸＰＳ、ＵＶ－Ｖｉｓ、ＩＲ和循环伏安法考察了催化剂各组分在反应前后存在状态，以及Ｐｄ（ＯＡｃ）２、Ｐｄ（ＯＡｃ）２／ＢＱ（苯醌）对环己烯的作用，ＦｅＰｃ对ＨＱ的催化氧化。讨论了Ｐｄ（ＯＡｃ）２／ＨＱ／ＦｅＰｃ催化环己烯氧化合成环己酮的作用机理。
The oxidation of cyclohexene to cyclohexanone catalyzed by Pd(OAc)2/HQ/FePcwas investigated in an acidic aqueous solution of acetonitrile. The role of each component incatalyst system during the oxidation of cyclohexene was examined by UV-Vis,IR,XPSspectroscopy and cyclic voltammetry, respectively. Based on the experimental results,themechanism of oxidation of cyclohexene catalyzed by Pd(OAc)2/HQ/FePc was discussed.
