✦ Synopsis

4,5-(Methoxymethylenedithio)-l,3-dithiole-2-chalcogenones 3 and 4 have been alkylated by using R3AI and RMgX (X = CI or Br)/TiCI4 complex reagent to give the title compounds 1 and 2. Cross-coupling of la--d with 5 furnished the mono-alkylated MET derivatives 6a--d, and the CIO 4 and PF 6 salts of 6b exhibited metallic conducting behavior for compressed pellets.
