It has been established that the two minor products obtained from the reaction of 6-cyano-tricyclo[5.5.0.0]dodeca-3,6,9,12-tetraene (3) with DDQ are 6-cyano-Dewar aceheptylene (5) and 5-cyanobenz[a]azulene (6), the formation of which show a new mode for the reaction of a substituted 8-cyanoheptafulvene with DDQ.
已经确定,由6-氰基-三环[5.5.0.0] dodeca-3,6,9,12-四烯(3)与DDQ反应获得的两个次要产物是6-氰基-杜瓦乙炔(5)。和5-氰基苯并[ a ] az(6),其形成显示了取代的8-氰基庚二烯与DDQ反应的新模式。
