Abstract
A strong electron pi-donor, vinylogue bis (ethylenedithio) tetrarhiafu lvalene (4) has been obtained in a six-step from 4,5-bis(benzoylthio) 1,3-dithiole-2-thione (7) (ca. 40% overall yield), its structure was f ully characterized by (1)HNMR, FT-IR, MS(EI) and elemental analysis. T he yield for the starting material TEA(2)[Zn(DMIT)(2)](2) is enhanced to 95% by an improved synthetic procedure described herein. Synthesis of aldehyde 14 was investigated in different solvent systems. Compound 10 and the new Horner-Wittig phosphonate (13) were first purified as a solid.
