The use of fused ring-1,2,4-benzotriazine derivatives as herbicides or plant growth regulators for the control of undesired plants or vegetation, compounds and compositions thereof, and processes for their preparation
The reactions of 4,5-dihydro[1,2,4]triazolo[3,4-c]benzo[1,2,4]triazines with aromatic aldehydes gave stable iminium salts which were deprotonated to give newazomethine imines. These new mesomeric betaines underwent 1,3-dipolar cyclization reactions to yield new tetra- and pentacyclic heterocycles. X-ray analysis and decoupling NMR experiments unambiguously supported the fact that these transformations
