1.2.4- Triazolines mass spectrometry

At present the major value of mass spectrometry to structural triazole chemistry appears to be in intricate heterocyclic reactions giving rise simultaneously not only to triazoles but many other heterocycles at the same time <81kgs694). Identification of unstable triazolines has been aided by mass spectrometry as well as by their NMR data (71BSF3296, 73bcj125o).
