【Abstract】 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.更多还原
