Tetraformyltetrathiafulvalene (TFTTF): Synthesis and Some Uses as a Precursor of Polyfunctionalised Tetrathiafulvalenes

Tetraformyltetrathiafulvalene has been prepared in a short, efficient synthesis and a few preliminary results emphasise its use as a precursor of polyfunctionalised tetrathiafulvalenes; a tetravinyl derivative is readily obtained via a Wittig reaction and has been shown, by its complexation with tetracyanoquinodimethane, to be a good ?-donor.

Tetraformyltetrathiafulvalene (TFTTF) and acetals, precursors of polyfunctionalized TTFs

A short synthesis of 1,3-dithiol-2-thiones bearing two aldehyde functionalities, free and/or masked as diethylacetals is described. They are shown to be convenient precursors for synthesizing di- and tetraformyl-TTF. When submitted to four-fold nucleophilic attacks, the latter readily affords new substituted derivatives such as the bis-(pyridazino)-TTF 8, the tetrakis-(hydroxymethyl)-TTF 9 and the tetravinylic-TTF 10 whose π-donor ability has been characterized.
