Mass spectra of 1,2,4‐triazoles—II: Alkyl 1,2,4‐triazoles

Organic Mass Spectrometry, 1973
AbstractThe 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.

1,2,4-Triazoles

2008
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, 1973
AbstractLa 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 ...

Fluorinated 1,2,3‐Triazoles: Terra Incognita in 1,2,3‐Triazoles Chemistry

ChemistrySelect
Abstract This review is devoted to the synthesis and application of fluoro‐substituted 1,2,3‐triazoles. The analysis of the available studies of fluorinated triazoles indicates exceptional value properties especially for biomedical research, despite the significant limitations of synthetic methods of their preparation.
