Synthesis of Tetrathiafulvalene Derivatives by the Usa of Organoaluminium Reagents

Bis(dimethylaluminium) salts of ethanedithiol, 1,2-benzenedithiol, and ethylenedithiol react with 1,3-dithiolane-2-carboxylate esters to give dihydro- and tetrahydro-tetrathiafulvalenes as well as tetrathiafulvalene derivatives.

Chalcogenation of Tetrathiafulvalene (TTF): Synthesis of Alkylthio-TTF and Alkylseleno-TTF Derivatives and X-Ray Crystal Structure of Ethylenediseleno-TTF (EDS-TTF)

The reaction of mono-lithiated tetrathiafulvalene (TTF) with elemental sulfur or elemental selenium at -78 deg C yields the transient species TTF-S(1-) Li(1+) and TTF-Se(1-) Li(1+), respectively, which have been trapped with a range of alkyl halides to yi
