Attempts to Synthesize Derivatives of the 2,3-Diazabicycloocta-5,7-diene System

The 2,3-diazabicycloocta-5,7-diene derivatives 1a and b could neither be obtained by a photoaromatization reaction of 8 nor by an electrolytic oxidation of the dicarboxylic acids 13a,b.Cycloadditions to 21 lead to derivatives of the title system.At temperatures above -10 deg C these undergo a -cycloreversion to produce the tetrahydrophthalazines 22.The thermal transformation of 21 to 22 is rationalized on the basis of a chain mechanism.
