Reaction of Diazoalkanes with 4-Substituted 1,2,4-Triazole-3,5(4H)-diones

Diazoacetic esters reacted with 4-substituted 1,2,4-triazole-3,5(4H)-diones (2) to give one-to-one adducts.Molecular weight determination, high-performance-liquid chromatography, and 2D n.m.r. spectroscopy showed that the adducts are monomers that associate in solution.The monomers are most likely 1,3,5-triazabicyclohexane-2,4-diones.The adducts were thermally isomerized to 3,6-disubstituted 1,3,5-triazine-2,4(1H,3H)-diones.Diphenyldiazomethane reacted with (2) to yield an azomethine imine, which underwent thermal dimerization followed by rearrangement.
