摘　　要：描述双（２，２－二羟基－１，１－联苯）硼酸的几种改良制法和性质．２，２－二羟基－１，１－联苯与（ＭｅＯ）３Ｂ，Ｈ３ＢＯ３－ＭｅＯＨ，Ｈ３ＢＯ３或Ｈ３Ｂ·ＳＭｅ２，在适宜介质中反应得到双（２，２－二羟基－１，１－联苯）硼酸溶剂合物；在碱存在下，它们高产率地转化为相应盐的溶剂合物。Some improved methods for the preparation of bis 2,2 dihydroxybiphenylboric acid and its preperties have been described.The solvolytes of bis 2,2 dihydroxybiphenylboric acid have been obtained by the reaction of 2,2 dihydroxylbiphenyl with H 3BO 3,H 3BO 3 CH 3OH,(CH 3O) 3B or H 3B·SMe 2 in proper media,respectively.They can be converted into solvolytes of diisopropylaminium bis 2,2 dihydroxybiphenylborate by reacting with (i Pr) 2 NH in high yield and the more polarity of a solvent is the stabler the solvolyte is.
