Reaction Conditions:
with bromine in chloroform at 20; for 24 h;
Steps:
1 Synthesis of 2,8-Dibromodibenzothiophene
To a slurry of dibenzothiophene (15.0 g; 0.0814 mol) in chloroform (80 ml) was slowly added bromine (10.5 ml; 32.6 g; 0.18 mol) in chloroform (20 ml). The red- brown reaction mixture was stirred at room temperature for 24 h and then solvent removed by distillation at atmospheric pressure. The residue was washed three times with methanol until the filtrate became almost colourless. The off-white solid was dried under vacuum at 75 °C. Yield 20.5 g (74 %). The product was sublimed to give an analytically pure colourless solid, 18.2 g (89 %). M.p 223°C (DSC, onset) and 227°C (DSC, peak) [ Lit., 226 °C, TCI]
