2,7-Dibromonaphthalene

A method for synthesizing organic optoelectronic semiconductor materials includes the following steps: 7.69 mmol of 2-anthraceneboronic acid (2.34 g), 3.5 mmol of General procedure: Under a nitrogen atmosphere, (27.4g, 60mmol) of compound 5-2-4 and (16.9g, 60mmol) of compound 8-8-1, (4.16g, 3.6mmol ) Tetrakis (triphenylphosphonium) palladium, (2.6g, 8mmol) tetrabutylammonium bromide, (2.4g, 60 mmol) sodium hydroxide, (30mL) water and (200mL) toluene were added to a 350mL three-necked flask, The reaction was stirred and heated at 80 C for 12 hours. The reaction was ended. Most of the solvent was removed by rotary evaporation. The organic solution was washed 3 times with dichloromethane, and the organic liquid was collected and purified by silica gel. The yield was 65%.Under a nitrogen atmosphere, (27.2 g, 100 mmol) of compound 11-6-1 and (28.4 g, 100 mmol) of compound 9-2-1, (6.9 g, 6 mmol) Tetrakis (triphenylphosphonium) palladium, (5.2g, 16mmol) tetrabutylammonium bromide, (4g, 100mmol) sodium hydroxide, (50mL) water and (300mL) toluene were added to a 500mL three-necked flask and heated at 80 C The reaction was stirred for 12 hours. The reaction was completed. Most of the solvent was removed by rotary evaporation, washed with dichloromethane and washed with water 3 times, and the organic liquid was collected and purified by silica gel column. The yield was 75%.
