Degradation of the petroleum component’s monomethylbenzothiophenes on exposure to light

The photochemical degradation of monomethylated benzo[b]thiophenes in aqueous solution was studied to elucidate the fate of crude oil components after an oil spill. One principal reaction pathway involves oxidation of the methyl group(s) to the carboxylic acids via aldehydes. Another pathway leads via oxidation of the thiophene ring to the quinone and then, after ring opening, to 2-sulfobenzoic acids as the ultimate products for all compounds. Opening of the benzo ring is also seen in which case thiophene aldehydes or ketones are formed.

Electrosynthesis of fluorinated benzo[ b ]thiophene derivatives

Anodic fluorination of benzo[b]thiophene derivatives provided a complex mixture of di- and trifluorinated products. On the other hand, anodic fluorination of 3-oxo-2,3-dihydrobenzo[b]thiophene and methyl 3-oxo-2,3-dihydrobenzo[b]thiophene-2-carboxylate gave the corresponding monofluorinated products selectively in moderate yields. Anodic fluorination of methyl alpha-(2-cyanophenylthio)acetate followed by intramolecular cyclization provided 3-amino-2-fluorobenzo[b]thiophene in excellent yield.

Palladium-catalyzed construction of heteroatom-containing pi-conjugated systems by intramolecular oxidative C-H/C-H coupling reaction

Synthesis of heteroatom-containing ladder-type pi-conjugated molecules was successfully achieved via a palladium-catalyzed intramolecular oxidative C-H/C-H cross-coupling reaction. This reaction provides a variety of pi-conjugated molecules bearing heteroatoms, such as nitrogen, oxygen, phosphorus, and sulfur atoms, and a carbonyl group. The pi-conjugated molecules were synthesized efficiently, even in gram scale, and larger pi-conjugated molecules were also obtained by a double C-H/C-H cross-coupling reaction and successive oxidative cycloaromatization.

Ladder-type pi-conjugated 4-hetero-1,4-dihydrophosphinines: A structure-property study

pi-Conjugated six-membered 1,4-dihydrophosphinines containing a heteroatom (Si, P, S) at the 4 position were synthesized and systematically studied. X-ray crystallographic analyses showed that the central six-membered heterocyclic rings are almost planar. The sum of the angles around the phosphorus atom increases by 23 from the trivalent phosphorus to the phosphonium atom in the thiaphosphinine system, which is consistent with the NMR spectroscopic studies. UV/Vis spectroscopy and theoretical calculations revealed that the communication between the phosphorus center and the benzothiophene moiety is enhanced by the incorporation of a sulfur atom into the molecular scaffold. The increased conjugation endows the thiaphosphinines with interesting emission properties. Theoretical calculations supported the postulation that the orbital coupling between the pi system and a sigma* orbital could be enhanced in the thiaphosphinine system, especially through a phosphonium center. Cyclic voltammetry studies revealed that the thiaphosphinine oxide, thiaphosphonium, and cis-diphosphinine oxide exhibit quasi-reversible reduction processes, which demonstrate that simple changes in the bridge heteroatoms help to efficiently tune the redox properties of the ladder-type 4-hetero-1,4-dihydrophosphinines.
