A number of 2-(alkylimino) and 2-(arylimino)-l,3-dithioles (aza DTFs) bearing push-pull substituents have been prepared under mild conditions according to the title procedure. This novel strategy relies upon the fact that the use of conjugated diisocyanides allows an effective synthesis of new extended tetrathiafulvalenes (TTFs). The two dithiole moieties are linked by a conjugated framework that incorporates a phenyl, biphenyl or azobiphenyl group. High and low temperature measurements are required in order to understand the complex 1H and 13C NMR spectra of the prepared mono-bis- and tris-(1,3-dithiole) derivatives. Their electrochemical oxidations are also described.
