The p-acetoxybenzylsulfanyl protecting group is compatible with the triethylphosphite 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 alkylated to give unsymmetrical tetrakis(alkylsulfanyl)tetrathiafulvalene derivatives.
