Facile Syntheses of 4-(2-Cyanoethylthio)-1,3-dithiole-2-thione and New Electron­ Donors with Two TTF Units and Compounds with Bis(1,3-dithiole-2-thione) Groups

Abstract

The synthetic conditions for the preparation of 4-(2-cyanoethylthio)-1,3-dithiole-2-thione (1) from TBA₂·[Zn(dmit)₂] were studied. Compound 1 was used to synthesize new electron donors with two tetrathiafulvalene (TTF) units. Other interesting compounds that are good precursors for tetrathiafulvalenophanes were also easily prepared from TBA₂·[Zn(dmit)₂].

Key words

electron donors - tetrathiafulvalene - cyclophane - 1,3-dithiole-2-thione - 1,3-dithiole-2-thione-4,5-dithiolate
