The stepwise syntheses of large [4+4] electron-rich thiamacrocycles, were performed using two types of building blocks, viz. 1,4-bis(bromomethyl)benzene or its dibutoxylated analogue and 4,5-bis(cyanoethylthio)-1,3-dithiol-2-thione. Alternatively, a multicomponent mixture of thiamacrocycles reaching in size from [2+2] to [6+6] units was generated a in a direct reaction of the bis(tetraethylammonium) bis(thioxo-1,3-dithiole-4,5-dithiol) zincate with 2,5-dibutoxy-1,4-bis(bromomethyl)-benzene.
