Abstract: 3-Aryl-5-arylidenerhodanines 3a-f react with 0,0-diethyl hydrogen phosphorodithioate 4 to yield 3,5-diarylthieto[2,3-d]thiazole-2-thiones 6a-f in a one-pot procedure. The compounds 6a-f undergo expansion of their thiete ring by the reaction with carbon disulphide, catalysed by lithium iodide, to afford the corresponding 3,7-diarylthiazolo[4,5-d]-1,3-dithiin-2,5- dithiones 7a-f in high yields under mild conditions.
