光催化苯羟基化制备苯酚反应的研究进展

Recent Progress in Photocatalytic Hydroxylation of Benzene to Phenol

苯酚是一种重要的有机中间体,在材料、农药、有机合成和药物领域应用广泛。工业上,采用多步异丙苯法制备苯酚,能源消耗高,环境污染严重且苯酚的选择性较低。近年来,随着光催化氧化技术的复苏,光催化苯羟基化制备苯酚迅速成为有机合成领域的研究热点。本文聚焦苯羟基化制备苯酚的光催化剂,综述了近年来在不同氧化剂条件下,光催化苯羟基化制备苯酚反应的研究进展,并对部分反应机理进行了讨论。

Phenol is an important organic chemical intermediate,widely exists in the materials,pesticides,organic synthesis and pharmaceutical fields.In industry,the preparation of phenol by multi—step isopropyl method has high energy consumption,serious pollution and low selectivity of phenol.In recent years,with the development of photocatalytic oxidation technology,photocatalytic hydroxylation of benzene to phenol has rapidly become a hot topic in field of photocatalytic organic synthesis.In this paper,the recent progress of the photocatalytic hydroxylation of benzene to phenol reaction is reviewed by the focus on the photocatalyst under the different oxidant conditions,and the reaction mechanism is discussed.
