Abstract

Homogeneous liquid-phase oxidation of alkenes (allylbenzene, cis-cyclooctene, 4-chlorostyrene, styrene, 2-norbornene, 1-methyl cyclohexene, indene, lemonine, and 1-hexene) were catalyzed by using vanadium complex [VO(hyap)(acac)₂] in existence of H₂O₂. The complex [VO(hyap)(acac)₂] was formed as a crystal by the reaction of [VO(acac)₂] and 2-hydroxyacetophenone (hyap) in the presence of methanol by refluxing the reaction mixture. Various analytical and spectroscopic techniques, namely FTIR, ESI–MS, UV–Vis, single-crystal XRD, and EPR, were used to analyze and optimize the structure of the complexes.

单核钒配合物与过氧化氢的烯烃均相催化氧化

摘要

使用钒配合物[VO（hyap）（）催化烯烃（烯丙基苯，顺式环辛烯，4-氯苯乙烯，苯乙烯，2-降冰片烯，1-甲基环己烯，茚，柠檬碱和1-己烯）的均相液相氧化acac）₂ ]存在于H ₂ O _2中。通过使[VO（acac）₂ ]与2-羟基苯乙酮（hyap）在甲醇的存在下，通过使反应混合物回流，使[VO（hyap）（acac）₂ ]络合物形成晶体。各种分析和光谱技术，例如FTIR，ESI-MS，UV-Vis，单晶XRD和EPR，用于分析和优化配合物的结构。
