[GRAPHICS]
A series of fully methylthiolated bi-, ter-, and quatertetrathiafulvalenes
have been synthesized using cross- and homocoupling reactions of tetrathiaf
ulvalenylzinc derivatives; the tetracation-tetraradical derived from the he
lical tetrathiafulvalene tetramer exhibits an intramolecular association of
the terminal cation-radicals.
