Deprotection of 2,3-bis(2′-cyanoethylthio)-6,7-(alkylidenethio)tetrathiafulvalene yielded tetrathiafulvalene dithiolate, the generate dithiolate was trapped by subsequent quenching with α,α-dichloro-p-xylene, yielding two new asymmetric tetrathiafulvalenes and two 'bis-bridged' bis-tetrahiafulvalenes. Electrochemical behaviour of asymmetric tetrathiafulvalenes and 'bis-bridged' bis-tetrathiafulvalenes were studied by cyclic voltammetry, and their UV-Vis spectra were discussed.
