A novel one-pot synthesis of annulated 2,2′-bipyridine ligands by inverse electron demand Diels–Alder reaction of 5,5′-bi-1,2,4-triazines
TL;DR: The Diels-Alder reaction of 5,5′-bi-1,2,4-triazines with cyclic enamines in the absence of a solvent leads to a range of symmetrical, annulated 2,2′-bipyridines in good yield as mentioned in this paper.

A New Synthesis of Pyrazolo[4,3-e][1,2,4]triazines via Acid Promoted Ring Closure of the Phenylhydrazones of 5-Acyl-1,2,4-triazines
TL;DR: A new acid-promoted ring closure method synthesizes pyrazolo[4,3-e][1,2,4]triazines from phenylhydrazones of 5-acyl-1,2,4-triazines in good yields, expanding the limited synthesis options for this pharmacologically active heterocyclic ring system.

1H- and 13C-NMR studies of σ-adducts of 1,2,4-triazine and some of its derivatives with amide ions and/or liquid ammonia
TL;DR: In this article, 1H- and 13C-NMR spectroscopic data have been presented for the formation of σ-adducts between a series of 1,2,4-triazines and amide ions and/or liquid ammonia at C(5) of the 1, 2, 4-triazine nucleus.
