The reactivity of unsubstituted 1,2,3-triazine was investigated using various nucleophilic and electrophilic reagents, molecular orbital calculations, and low temperature nmr measurements

Journal of The Chemical Society, Chemical Communications | 1980

Synthesis, oxidation, and reduction of monocyclic 1,2,3-triazines

Akio Ohsawa; Heihachiro Arai; Hidefumi Ohnishi; Hiroshi Igeta

Alkyl substituted monocyclic 1,2,3-triazines and their 1-and 2-oxides have been synthesized; catalytic reduction (on Pd–C) of the triazines afforded their 2,5-dihydro compounds.

Chemical & Pharmaceutical Bulletin | 1986
