The arylazo derivatives (2) of 3-methyl-2-isoxazolin-5-thione were prepared. Alkylation of 2 with alkyl halides results in the formation of the S-alkyl derivatives (5). The S-acetate esters undergo thermal isomerisation to the corresponding 1,2,3-triazole derivatives (6). The thiones 2 condense with hydrazines and primary amines to afford the corresponding 5-hydrazones and 5-imines (8) and (10), respectively. Treatment of 2 with hydrazine hydrate and Phenylhydrazine in boiling alcohol effects ring cleavage with the formation of 9.
