Participants

Reaction Steps

Under an Ar atmosphere, 3,5-dicarbazolylbromobenzene (4.87 g, 0.01 mol) and 100 mL THF (tetrahydrofuran) were added into a 250 mL single-necked flask, then 9.4 mL n-BuLi (n-butyllithium) (1.6 M n-hexane solution) was added, stirred and reacted at −78° C. for 1.5 h. After this, trimethyl borate was added and reacted for 12 h, and then 20 mL hydrochloric acid solution was added, acidified for 0.5 h. After the reaction was completed, we carried out liquid separation, drying, and concentrating under reduced pressure, and obtained 3,5-dicarbazolylphenylboronic acid by column chromatography. The reaction process is as follows:
