- THREE COMPONENT CONDENSATION OF 3-AMINO-1,2,4-TRIAZOLE WITH CARBONYL COMPOUNDS. A NEW SYNTHESIS OF 1,2,4-TRIAZOLOPYRIMIDINES
-
Three component condensation of 3-amino-1,2,4-triazole with an aromatic aldehyde and ketone gives 1,2,4-triazolopyrimidines.An x-ray structural investigation of 5-phenyl-4,5,6,7-tetrahydro-1,2,4-triazolobenzoquinazoline was undertaken in order to determine the course of this reaction.

- CARBOCYCLE ANNELATED 1,2,4-TRIAZOLOPYRIMIDINES
-
Reaction of 3-amino-1,2,4-triazole with mono- and dibenzalcycloalkanones gives 4,7-dihydro-1,2,4-triazolopyrimidines annelated by five-, six-, or seven-membered carbocycles.They can be dehydrogenated to the corresponding heteroatomics.The spectro-luminescent properties of the compounds obtained are discussed.
