摘要 通过硅胶依次与氯化亚砜、苯酚和氯磺酸的反应制得了新型的硅胶负载苯磺酸催化剂.该催化剂在无溶剂和微波辐射条件下能高活性、高选择性地催化烯丙基芳基醚的Claisen重排反应,快速、高产率地得到烯丙基酚,且催化剂具有易回收、可重复利用和环境友好等优点. The novel catalyst,silica-supported benzenesulfonic acid,is prepared by reactions of silica gel with thionyl chloride,phenol and chlorosulfonic acid in turn.Silica-supported benzenesulfonic acid could actively and selectively catalyze Claisen rearrangement of allyl aryl ethers to afford allylphenols in high yield under solvent-free and microwave irradiation conditions.Silica-supported benzenesulfonic acid has recoverable,reusable and environmentally benign features.
