Publisher Summary This chapter focuses on the chemistry of monocyclic1,2,3-triazoles as much of the chemistry of benzotriazoles and other fused systems has little in common with monocyclic triazole chemistry and provides a broad survey of methods of synthesis and reactions of triazoles. There has been considerable interest in 1,2,3-triazoles as light

Mass spectra of 1,2,4‐triazoles—II: Alkyl 1,2,4‐triazoles
Organic Mass Spectrometry, 1973AbstractThe mass spectra of monomethyl 1,2,4‐triazoles contain fragment ions produced by specific cleavage of the heterocyclic ring. A major fragmentation from many molecular ions involves the elimination of HCN, but loss of N2 is either very small or completely absent.

This chapter provides a critical update on developments in the chemistry of 1,2,4-triazoles over the last decade. 1,2,4-Triazoles have remained the topic of much research, primarily due to their ubiquitous presence in many pharmaceutical agents and, more recently, in other functional materials with uses in engineering as corrosion inhibitors and in ...

Fragmentation de Triazoles Sous L'Impact Electronique—II 1,2,3‐Triazole
Organic Mass Spectrometry, 1973AbstractLa similitude de comportement des 1,2,4‐ et 1,2,3‐triazoles sous l'impact électronique est attribuée à la formation de structures ioniques communes. L'étude des transitions métastables correspondant à al perte d'une molécule d'azote semble indiquer que, dans le cas du 1,2,3‐triazole, les deux formes tautoméres coexistent à l'état gzaeux et qu ...
