苯甲酸类在甲苯中与氯化亚砜作用生成的苯酰氯,在PTC 下用硼氢化钠水溶液还原成芳香醇,继而与氯化亚砜反应生成氯苄类,可一锅合成。从几种苯甲酸制备相应氯苄
Benzoic acid Benzene chloride formed by the action of thionyl chloride in toluene is reduced to an aromatic alcohol by an aqueous solution of sodium borohydride under a PTC and then reacted with thionyl chloride to form benzyl chlorides. One-pot synthesis can be performed. The corresponding benzyl chloride was prepared from several benzoic acids
