These common heterocyclic compound, 61921-39-9, name is 4-Bromotetraphene, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Application In Synthesis of 4-Bromotetraphene
Example 27 Synthesis of 4-(benz[a]anthracen-4-yl)benz[a]anthracene Preparation analogous to Example 7. 9-Bromo-10-(2-naphthyl)anthracene is replaced by 15.4 g (50 mmol) of 4-bromobenz[a]anthracene. Recrystallisation four times from o-dichlorobenzene (about 15 ml/g); sublimation (p=5*10-5 mbar, T=320 C.). Yield: 16.8 g (37 mmol), 74.0%, purity 99.9% (HPLC), Tg=130.3 C.
The synthetic route of 4-Bromotetraphene has been constantly updated, and we look forward to future research findings.
