苯酚的高选择性邻位氯化ＧｎａｉｍＪＭ等［ＴｅｔｒａｈｅｄｒｏｎＬｅｔｔ，１９９５；３６：３８９３］苯酚在非极性溶剂中，以胺催化，用硫酰氯进行氯化速度快，特别是一氯比反应的邻位取代选择性高。例如，苯酚与等摩尔硫酰氯及０．８％摩尔二异丁基胺于７０℃反应１... Highly selective ortho-chlorination of phenol GnaimJM et al [Tetrahedron Lett, 1995; 36: 3893] Phenols are catalyzed by amines in non-polar solvents and chlorinated with sulfuryl chloride at high rates, especially in the ortho- High selectivity instead. For example, the reaction of phenol with equimolar thionyl chloride and 0.8 mole% of diisobutylamine at 70 ℃ 1 ...
