“…The calculated differences of chemical shifts between protons A and B are as follows: chair C 0.32 ppm, boat B 0.29 ppm. periplanar protons of the N-methyl groups and two protons in 3 and 4 positions shows that the amidic parts of the diazocinedione ring are planar (13,14). This is the case only in the boat conformation in which the two ~r o t o n s A and A' above the benzene ring appear at lower frequencies than the two other ones.…”

To expand on the limited number of examples that exist in the literature for the solid-state photodenitrogenation of azoalkanes, a series of crystalline 7-alkyl-2,3,7-triazabicyclo[3.3.0]oct-2-ene-6,8-diones with varying 4,4-substituents were prepared. Their photochemical behavior in solution and in the solid state was dependent on the 4,4-substitution of the 1-pyrazoline ring, with unsubstituted pyrazoline giving a mixture of products both in solution and in the solid state. Diphenyl substituted pyrazolines denitrogenate spontaneously in solution but require light exposure to react quantitatively in the solid state. t-Butyl-phenyl substituted pyrazolines were shown to denitrogenate both chemo- and diastereoselectively in solution and in the solid state to yield a single product in quantitative yield.
