Reaction Steps
Preparation analogous to Example 7. 9-Bromo-10-(2-naphthyl)anthracene is replaced by 4.1 g (25 mmol) of benzene-1,4-diboronic acid. Recrystallisation five times from o-dichlorobenzene (about 20 ml/g); sublimation (p=5×10−5 mbar, T=400° C.). Yield: 11.1 g (21 mmol), 84.0%, purity 99.9% (HPLC).
