## Abstract The mass spectra of monomethyl 1,2,4โtriazoles 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 N~2~ is either very small or completely absent. No N or H scrambling o
Condensation of 4-methylsulfonylaniline with aryl aldehyde in ethanol-tetrahydrofuran afforded the imino compound 3. 1,3-Cycloaddtion of diazomethane with compound 3 followed by oxidazation of the triazoline 4 with potassium permanganate gave 1-(4-methylsulfonylphenyl)-5-aryl-1,2,3-triazoles 5. Simi
