PRECURSEURS DE NOUVEAUX TETRATHIAFULVALENES: ALCOYLTHIO-4 AMINO-2 DITHIOLES-1,3 ET LES ALCOYLTHIO-4 ALCOXY-2 DITHIOLES-1,3 PREPARES A PARTIR DES DITHIOLES MESOIONIQUES

NaBH₄ reduction of mesoionic 2-amino 4-thioxo 1,3-dithioles in the presence of an alkyl halide is a new route to 4-alkylthio-2-amino-1,3-dithioles which are easily converted into 2-alkyloxy-4 alkylthio 1,3-dithioles.In an acidic medium, these compounds lead in good yields to new dissymetrically substituted tetrathiafulvalenes.
