Nitric Acid → 2-Nitro-9,10-dihydrophenanthrene

Participants

Reaction Steps

First, 300 g of 9,10-dihydrophenanthrene were dissolved in 2 L of acetic acid, and then 450 mL of fuming nitric acid (d=1.50) were dropped to the mixture. The reaction solution was stirred at room temperature for 7 hours. The reaction solution was poured into 5 L of water, and then the precipitated crystal was separated by filtration and recovered. The resultant crystal was washed with water and methanol, and was then dried under reduced pressure. Thus, 280 g of an orange crystal were obtained (in 74% yield).
