  摘要：

  The title compounds are among the first tetrathiafulvalenes with annulene spacers, here with tetraepoxy-[22]annulene(2.1.2.1) (see 3a), tetraepithio[22]annulene(2.1.2.1) (see 3b), and diepithiodiepoxy[22]annulene(2.1.2.1) (see 23) units. The annulenoid tetrathiafulvalenes 3a and 3b are prepared by cyclizing McMurry coupling of the 5,5'-(1,3-benzodithiol-2-ylidenemethylene)bis[furan- or thiophene-2-carbaldehydes] (8a or 8b, resp.) or by Wittig reaction of (1,3-benzodithiol-2-yl)tributylphosphonium tetra fluoroborate (13b) with tetraepoxy[22]annulene(2.1.2.1)-1,12-dione 20 (formation of 3a) or diepithiodiepoxy[22]annulene(2.1.2.1)1,12-dione 22 (formation of 23). The annulenoide tetrathiafulvalene 3a is obtained as a mixture of the isomers (E,E)- and (Z,Z)-3a. At 130 degrees, (Z,Z)-3a rearranges quantitatively into the (E,E)-isomer. Isomer (E,E)-3a is a dynamic molecule, where the (E)-ethene-1,2-diyl bridges rotate around the adjacent sigma -bonds, The tetraepithioannulene derivative 3b as well as 23 only exist in the (Z,Z) -configuration. The oxidation of (E,E/Z,Z)-3a with Br-2 yields the annulene -bridged tetrathiafulvalene dication (E,E)-3a(Ox), while with 4,5-dichloro-3,6-dioxocyclohexa-1,4-diene-1,2-dicarbonitrile (DDQ) obviously only the radical cation 3a(Sem) is formed, which belongs to the class of cyanine-like violenes. The annulenoide tetrathiafulvalenes 3b and 23, which exist only in the (Z,Z) -configuration, obviously for steric reasons, cannot be oxidized by DDQ. Electrochemical studies are in agreement with these results.

  The title compounds are among the first tetrathiafulvalenes with annulene spacers, here with tetraepoxy-[22]annulene(2.1.2.1) (see 3a), tetraepithio[22]annulene(2.1.2.1) (see 3b), and diepithiodiepoxy[22]annulene(2.1.2.1) (see 23) units. The annulenoid tetrathiafulvalenes 3a and 3b are prepared by cyclizing McMurry coupling of the 5,5'-(1,3-benzodithiol-2-ylidenemethylene)bis[furan- or thiophene-2-carbaldehydes] (8a or 8b, resp.) or by Wittig reaction of (1,3-benzodithiol-2-yl)tributylphosphonium tetra fluoroborate (13b) with tetraepoxy[22]annulene(2.1.2.1)-1,12-dione 20 (formation of 3a) or diepithiodiepoxy[22]annulene(2.1.2.1)1,12-dione 22 (formation of 23).
