3-Mercaptoisoxazoles (XI) were synthesized from 3-allylsulfinylisoxazoles (II). The reaction of II with triphenylphosphine in the presence of acetic anhydride gave the corresponding 3-acetylthioisoxazoles (VII). The thioacetates (VII) were converted into 3-mercaptoisoxazoles (XI) by reaction with silver nitrate and subsequent treatment of the resulting silver salts (X) with hydrogen sulfide. The thiols (XI) were oxidized in air to give the corresponding disulfides (XIV). In alkaline solution, 3-mercapto-5-phenylisoxazole (XIb) was decomposed into benzoylacetonitrile (IX) and sulfur.
