C. Gemmell et al., SYNTHESIS OF UNSYMMETRICAL TETRAKIS(ALKYLSULFANYL)TETRATHIAFULVALENE DERIVATIVES, Journal of the Chemical Society. Perkin transactions. I, (19), 1994, pp. 2715-2720
The p-acetoxybenzylsulfanyl protecting group is compatible with the tr
iethylphosphite mediated cross-coupling of 4,5-bis(alkylsulfanyl)-1,3-
dithiol-2-ones, providing access to bis(protected)-tetrathiafulvalenes
, and thus to tetrathiafulvalenedithiolate dianion 10, which can be al
kylated to give unsymmetrical tetrakis (alkylsulfanyl)tetrathiafulvale
ne derivatives.
