13synthesis methods

Product Name:9-Bromo-10-phenylanthracene
CAS Number:23674-20-6
Molecular formula:C20H13Br
Molecular Weight:333.22

9-Phenylanthracene (2.5g, 9.83mmol) and NBS (2.1g, 11.8mmol) were dissolved in 80mL CHCl3. Then the mixture was heated to 60°C for 2h under N2. After cooled to room temperature, 20 mL water was added. And the mixture was extracted with CH2Cl2. The organic extracts were dried over anhydrous MgSO4 and concentrated by rotary evaporation.The crude product was recrystallized from methanol to get a green-yellow powder (2g, 61.2%). 1H NMR (500 MHz, CDCl3) δ 8.67 – 8.61 (m, 2H), 7.71 – 7.65 (m, 2H), 7.64 – 7.56 (m, 5H), 7.45 – 7.37 (m, 4H). EI-MS (m/z): Calculated for C20H13Br: 333.22. Found [M+]: 332.30.

Yield:23674-20-6 98%

Reaction Conditions:

with N-Bromosuccinimide in chloroform at 60; for 1 h;Inert atmosphere;

Steps:

1.2 Synthesis of 9-bromo-10-phenylanthracene (2)

9-phenylanthracene (1) (2.54 g, 10.0 mmol), N-bromosuccinimide (2.14 g, 12.0 mmol) and chloroform (200 mL) were heated at 60 ° C. for 1 hour under a nitrogen atmosphere. After cooling to room temperature, the solvent was distilled off under reduced pressure. After re-dissolving in acetone, it was reprecipitated in methanol and filtered to obtain a yellow solid (3.26 g, yield 98%).
