【摘要】 用乙酸酐保护对羟基苯甲酸的羟基,再经氯化亚砜酰氯化、与苯酚成酯得到对乙酰氧基苯甲酸苯酯,最后经脱乙酰保护基和Fries重排得到4,4’-二羟基二苯甲酮,总收率68%。更多还原

【Abstract】 Dihydroxybenzophenone was synthesized in 68% overall yield from p-hydroxybenzoic acid by hydroxyl group protection, chlorination and esterification with phenol to give phenyl 4-acetoxybenzoate followed by deprotection and Fries rearrangement.更多还原
