Nitric Acid → 9-Bromononanoic Acid

Temperatur

0 °C

9-Bromo-1-nonanol (4 g, 18 mmol) was placed in a flask, cooled on an ice bath, and concentrated nitric acid (40 mL) was slowly added. The solution was stirred at 0° C. for 30 minutes then allowed to warm to room temperature and stirring continued overnight. The solution was poured onto ice and extracted with DCM (3×150 mL). The combined extracts were washed with water (3×150 mL) and the solvent then removed in vacuo to give an oil 3.82 g (94%);
