cis- and trans-5-Acetoxy-7a-nitro-5,7-dihydroindane are formed as well as the 4- and 5-nitroindanes when indane is reacted with nitric acid and acetic anhydride. These adducts both decompose on standing by loss of nitrous acid forming 5-acetoxyindane. The cis isomer is obtained in greater amount and it undergoes elimination less readily than the trans.
