- 論文の詳細を見る
The photocyclization of diarylfumaronitriles in aqueous ethanol is influenced by pH. The product ratio of 9,10-dihydro-9,10-dicyanophenanthrenes (IV) decreases with decrease in pH. Discussion is given on the acid-catalyzed isomerization of the 4a,4b-dihydrophenanthrenes to IV from results of observation of the colored intermediate.
