New conducting polymers, including poly[thieno[3,2-b][1]benzothiophene] (poly-TBT) and poly [6-methoxythieno[3,2-b][1]benzothiophene] (poly-MeOTBT) were electrosynthesized by anodic oxidation of the corresponding monomers in 0.1 M LiClO4 acetonitrile solution. Poly-TBT and poly-MeOTBT electroactive films were formed on platinum electrodes and characterized spectroscopically. FT-IR studies show that both polymers present couplings occurring on the thiophene moiety and the phenyl ring, with a step-like structure. MALDI-TOF mass spectrometry indicates that poly-TBT and poly-MeOTBT films are mainly constituted of short-chain oligomers. The results of molecular orbital (MO) calculations performed on the basis of a radical-cation electropolymerization mechanism are in good agreement with our spectral data.

We report Pd-catalyzed ortho-C-H methoxylation and chlorination of benzaldehydes by employing monodentate transient directing groups (TDGs) as an alternative strategy to bidentate TDGs. More importantly, a single crystal of benzaldehyde imine ortho-cyclopalladium intermediate was successfully obtained, and its structure was unambiguously determined by X-ray diffraction, which clearly showed that it was a binuclear palladium species bridged by a pyridone ligand. The utility of this approach was further demonstrated through the synthesis of key intermediates of natural products and drugs.

-
Paragraph 0207-0209, (2017/08/30)
The invention discloses an efficient compounding method of a 3-substitued-benzo five-membered heterocycle-2-carbonyl compound. According to the method, a 3-substitued-benzo five-membered heterocycle-2-alcohol compound is subjected to a halogenated oxidation reaction by a halogenating reagent to generate the corresponding 3-substitued-benzo five-membered heterocycle-2-carbonyl compound. The efficient compounding method has the advantages that raw materials are easy to get, reaction conditions are mild, and reaction selectively and yield are high.

supporting information, p. 2678 - 2683 (2016/09/03)
A facile method to synthesize 3-halobenzo-heterocyclic-2-carbonyl compounds is described. Mechanistic studies suggested that a halo-cyclization process, which generated the unstable spiro-acetal transition state and readily convertible to the corresponding carbonyl compound might be involved. Diverse 3-halobenzo-heterocyclic-2-carbonyl compounds could be synthesized with up to 95 % yield in mild conditions with inexpensive starting materials. (Figure presented.).

Domino Vilsmeier-Haack/ring closure sequences: A facile synthesis of 3-chlorobenzo[b]thiophene-2-carbaldehydes
Paul, Nidhin,Muthusubramanian, Shanmugam
scheme or table, p. 3743 - 3746 (2011/08/06)
Vilsmeier's reagent treatment of substituted diphenacyl sulfides or diphenacyl disulfides has led to the formation of a series of benzfused 3-chlorothiophene-2-carbaldehydes by a Domino Vilsmeier-Haack reaction/ring closure sequence, opening a new route for the synthesis of 3-chlorobenzo[b] thiophene-2-carbaldehydes and their benzfused analogues. A plausible mechanism has been proposed.
