Abstract:
1,2,3,4-Tetrahydro-1-methyl-3-(p-bromophenyl)-4,6-diphenyl-s-tetrazine (3a), exhibiting ring .dblharw. chain tautomerism in solns, exists as the ring tautomer in the solid phase, as proved by x-ray crystal structure detn. However, the 6-acetyl analog 3b acquires the chain form in the cryst. state. Crystallog. data and at. coordinates are given.
