Abstract

[2+4] Cycloaddition of oligomeric 1,3-dithiole-2,4,5-trithione (2) and tetrathiafulvalene (TTF) leads to the formation of the new cycloadduct 6-(1,3-dithiol-2-ylidene)-4a,7a-dihydro-2-thioxobis[1,3]dithiolo[4,5-b :4',5'-e][1,4]dithiin (3); its oxidation or reaction with a base and subsequent methylation afford 6-(1,3-dithiol-2-ylidene)-2-thioxobis[1,3]dithiolo[4,5-b:4',5'-e][1,4] dithiin (4) and 4-[2(1,3-dithiol-2-ylidene)-1,3-dithiol-4-ylthio]-5-methylthio-1,3-dit hiole-2-thione (5), respectively.
