4-(4-NITRO-BENZOYL)-BENZOIC ACID synthesis

4synthesis methods
-

Yield:7377-13-1 85%

Reaction Conditions:

with chromium(VI) oxide;sulfuric acid in acetic acid at 0 - 20;

Steps:

4-(4-Nitrobenzoyl)benzoic acid (7)

To an ice-cooled mixture of 6 (20.00 g, 0.08 mol) in glacial acetic acid (150 mL) was added sulfuric acid (28 mL) slowly to keep the temperature below 5 °C. Chromium oxide (28.00 g, 0.28 mol) was added in small portions at such a rate that the temperature did not exceed 10 °C. The reaction solution was stirred at room temperature overnight, then ice water (20 mL) was added. The precipitated solid was filtered, washed with water and dried to afford 7 22.0 g (85%) of a white powder. mp 254-256 °C.
