Cis-ethylenic analogues 1 and ortho-benzenic analogues 2 of TTF undergo a rapid acid mediated intramolecular cyclization into the corresponding cycloisomers 1' and 2' whose structures are confirmed by X-ray diffraction; as shown by cyclic voltammetry, compounds 1 may act as convenient precursors of organic metals.
