We propose an improved general method for the synthesis of tetrathiafulvalene and its methylated derivatives.TTF is obtained in a five steps preparation offering a high Overall yield. Concerning the unsymmetrically methylated tetrathiafulvalenes, four different procedures are analysed.It is shown the best routes to prepare trimethyltetrathiafulvalene are a WITTIG type reaction, and a selective synthesis based on a WITTIG-HORNER reaction.The monomethyltetrathiafulvalene has been isolated in a 96percent state of purity.
