Synthesis, crystal structure, and polymerization of butterfly-shaped thieno[3,2-b]thiophene oligomers

A series of new butterfly-shaped thieno[3,2-b]thiophene oligomers with phenyl and thiophene units were synthesized through Suzuki coupling and Stille coupling reactions. The optical and thermal properties of these materials can be tuned by varying both su

1,1'2,2'-Tetrathiafulvalenes, III. - Syhthesis, Properties, and Reactions of 3,3'-Bi(3H-1,2-dithiolylidenes)(1,1',2,2'-Tetrathiafulvalenes)

1,1',2,2'-tetrathiafulvalenes 1 can be prepared by different methods from the cations of 1,2-dithiolylium salts 4 which are either unsubstituted or appropriate substituted in 3-position (instead of 3-Cl also H or SCH3).The structure of 1 is substantiated by chemical arguments.IR and 13C-NMR spectra support the absence of thioxo groups. - Like the 1,1',3,3'-isomers 2 the 1,1',2,2'-tetrathiafulvalenes are disposed to stepwise donation of electrons with formation of the radical cation and dication salts 25 or 11, respectively, as well as to the formation of charge transfer complexes with tetracyanoethylene, tetracyanoquinodimethane, and 2,3-dichloro-5,6-dicyanobenzoquinone.Tris(triphenylphosphine)rhodium(I) chloride and tetrakis(triphenylphosphine)platinum(O) yield complexes with 1a. - Thermolysis of 1 produces thienothiophenes 6.Partial desulfuration of 1a, for example, is also feasible with oxidizing agents like lead(IV) acetate.Selenium dioxide, however, gives the corresponding thienofuran 41.The reaction with trialkyl phosphites yields a disulfide - probably the 2,2'-bi(2H-thietylidene) 38 - the thermolysis of which gives the thienothiophene 6a. - Compounds 1a and 1c do not react with dimethyl acetylenedicarboxylate, isothiocyanate, several 1,3-dipoles (azides), and also not with elementary sulfur, however, 1e forms with sulfur the 3H-1,2-dithiol-3-thione 5e (X = S).
