Abstract
Reactions of phenylhydrazinium thiocyanate with various ketones and aldehydes gave 1-phenyl-3-alkyl-5-mercapto-Δ4-1,2,4-triazoline compounds in 80–90% yield by the cycloaddition of thiocyanic acid to the phenyl-hydrazones intermediately formed from phenylhydrazine and the ketones or aldehydes. Their structure were determined by elemental analyses, spectral data (IR, NMR, and MS) and chemical reactions. Many 2-phenyl-thiosemicarbazone and 1-phenyl-1,2,4-triazole derivatives were synthesized in good yields.
