Abstract
lkylthio-5-(p-nitro-phenyl)-1,3-dithiole-2-thiones 4a-e, 4-alkylthio-5 -(p-, bzw. o-cyano-phenyl)-1,3-dithiole-2-thiones 4f, 4g, 4-alkylthio- 5-pivaloyl-1,3-dithiole-2-thiones 4h-j und 5-methylthio-2-thioxo-1,3-d ithiole-4-carboxylic acid N-methyl-p-chlor- bzw. -p-methoxy-anilides 4 k, 4l are obtained by reaction of the O-ethyl-S-substituted dithiocarb onates 3 with carbon disulfide/potassium tert. butoxyde in dry DMF and alkylation reagent. Treatment of 1,3-dithiole-2-thiones 4a-c with mer curic acetate give 1,3-dithiole-2-ones 5a-c. Carbonyl stretching frequ encies of 2-oxo-substituted five-membered heterocycles I are discussed .
