C–H bond activation of benzene and thiophene by photochemically generated rhenocene cation

“…On irradiation, perhaps the excited 7 and 8 liberate the thiophene derivatives to generate A, and then A activates the C−H bond of the thiophene derivatives to give 5 and 6. The η 1 -S-coordinated complexes are considered to be the intermediates for C−S bond activation [4,5], but from 7 and 8, formation of the C−S bond activation products was not observed.…”

“…Recently we synthesized a cationic rhenocene acetonitrile complex [Cp 2 Re(NCMe)](BF 4 ) (1) by photolysis of the cationic rhenocene dihydride complex [Cp 2 ReH 2 ]BF 4 (2) in acetonitrile. We found that 1 was a convenient precursor for photochemically generating the rhenocene cation [Cp 2 Re] + (A) a species isoelectronic and isostructural to Cp 2 W, and the photolysis of 1 in the presence of benzene or thiophene afforded the C−H bond activation products 3 and 4a in high yields [3] (Scheme 2).…”

Synthesis, Aggregation‐Induced Emission, and Electroluminescence of Dibenzothiophene‐ and Dibenzofuran‐Containing Tetraarylethenes

“…Thiophene is considered as an excellent material with an electron-rich conjugation system in its oligomer form and polymer structures. [8][9][10][11][12][13][14] Dibenzothiophene (DBT) has an even more planar, fused polycyclic aromatic hydrocarbon structure than thiophene, [15,16] and it is thus considered to have superior electronic properties than those of thiophene. [15][16][17][18] With similar electronic affinity for sulfur and oxygen atoms, dibenzofuran (DBF) is another potential candidate for OLED applications.…”

Insertion of Pt into CH and CS bonds of thiophene derivatives. The X-ray crystal structure of a thiaplatinacycle of 3,6-dimethylthieno[3,2-b]thiophene

“…Rh, Ir, Pt, Fe, W) oxidatively inserts into the C Ã/S bonds of thiophenes, benzothiophenes and dibenzothiophenes [6 Á/13]. Thiairidacycles [13] and thiaplatinacycles [10,14] have both been shown to effect HDS. This article reports on the oxidative reactions of platinum(0) with the thiophene derivatives 3,6-dimethylthieno [3,2-b]thiophene (1), 2,2?-bithiophene (2) and 1-methyl-2-(2-thienyl)pyrrole (3) (Scheme 1).…”
