Synthesis and properties of new .PI.-donor sulfur heterocycles
摘要:
Two new pi-donors related to bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF, 2) have been synthesized. These are the vinylogue 5 of BEDT-TTF and the mixed-vinylogue 4 related to TTF and BEDT-TTF.

alkyne-1-thiolate gives new tetrathiafulvalene-type vinylogue extended π-donors in a one pot reaction. The solvent-/base-system used (acetonitrile/NaH) was optimised for the synthesis of 1,3-dithiole-2-thiones via this route. Efficient synthesis of the important 4-formyl-1,3-dithiol-2-thione and its coupling to 2,6(7)-bisformyltetrathiafulvalene is presented. Preparation of a number of new 1,4-dithiafulvenes

2-Diformylmethylene-1,3-diselenole was prepared and condensed with dithiolium phoshonium bromides and dithiolium phosphonates in the presence of base to give dendralene-type vinylogs of TTF bearing a 1,3-diselenole moiety. The electrochemistry of these dendrimers was studied. SEEPR measurements were also carried out. Calculations were carried out on the radical cations and correlated with the EPR values
