| Research Abstract |
The efficient syntheses of unsymmetrical tetrathiafulvalenes (TTFs), as well as symmetrical TTFs, were accomplished by the Lewis acid-mediated reactions of organotin compounds with electrophiles. The synthesis of unsymmetrical TTFs could be carried out by the Me_3Al-promoted noncoupling reactions without tedious separation procedure. In addition, this synthetic method could also be applicable to the preparation of TTFs-fused donors. Moreover, BEDT-TTF derivatives condensed with heterocycles could be synthesized systematically via the BF_3-promoted reaction. We have accomplished the development of new organic metals based on (1) the DHTTF (dihydrotetrathiafulvalene) derivative, (2) the DSDTF (diselenadithiafulvalene) derivative, (3) TTFs-fused donors, and (4) the BEDT-TTF derivative fused with 1,4-dioxane ring.
