An efficient synthesis of new long-chain substituted tetrathiafulvalene derivatives involving two tetrathiafulvalene moieties

Derivatives involving two tetrathiafulvalene moieties linked by an alkylenedithio bridge and long-chain substituents were synthesized by the condensation of alkylenedithiobis(1,3-dithiole-2-triphenyl-phosphonium) perchlorates and 2-ethylseleno-4-heptadecyl-1,3-dithiolium tetrafluoroborate in the pre...

Summary:Derivatives involving two tetrathiafulvalene moieties linked by an alkylenedithio bridge and long-chain substituents were synthesized by the condensation of alkylenedithiobis(1,3-dithiole-2-triphenyl-phosphonium) perchlorates and 2-ethylseleno-4-heptadecyl-1,3-dithiolium tetrafluoroborate in the presence of triethylamine. The derivative involving a hexadecylethylenedithio substituent was synthesized by the coupling of the corresponding 1,3-dithiol-2-one and 1,3-dithiole-2-thione derivatives in the presence of triethyl phosphite.
