Article abstract of DOI:10.1016/S0040-4039(96)02063-1

The cycloaddition of hex-3-yn-2,5-dione onto a π-CS₂ iron complex 3 and on3-thioxo-1,2-dithioles affords diacetylated intermediates which can be readily converted into di or tetraacetylated derivatives of the 1,3-dithiole (5,6) and tetrathiafulvalene (2,8) series, some representative electrochemical and structural features of which being also presented.
