STUDIES ON THE SYNTHESIS OF THE METABOLITES OF YEKULING．A SULFURORGANIC FUNGICIDE

This paper reports the synthesis of the metabolites．1,3-dfthiolan-2-ylidenehydrazine(I)，acetic acid 1,3-dithiolan-2-ylidenehydrazide(II)，pyruvic acid 1,3-dithiolan-2-ylidenehydrazone(III)and benzoic acid l，3-dithiolan-2-ylidenehydrazide-S-oxide(IV)of yekuling，a new sulfurorganic fungicide(benzoic acid 1，3-dithiolan-2-ylidenehydrazide)．The structures of all the compounds synthesized were characterized by elemental analysis，IR，UV，MS and ¹HNMR spectra．
