Reaction Conditions

Reaction Steps

An amount of 3 g (6.21 mmol) of 9-bromo-7,12-diphenylbenzofluoranthene synthesized in the same manner as in Exemplary Synthesis 1 was dissolved in dehydrated THF and cooled to −80° C. Then, 4.3 ml (6.8 mmol) of a solution of n butyllithium in n-hexane was added dropwise. Forty minutes later, 1.81 g (12.4 mmol) of triethyl borate was added. After two-hour reaction, a diluted hydrochloric acid solution was passed and allowed to stand for 12 hours. Then, the separated organic layer was recrystallized to obtain 1.51 g (3.37 mmol) of 7,12-diphenylbenzofluoranthene-9-boronic acid. The yield was 54.3%.
