Novel products in the reaction of 6-cyanotricyclo[5.5.0.0]dodeca-3,6,9,12-tetraene with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone
Abstract
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.
