Effect of Alkyl Chain Length and Linker Atom on the Crystal Packing in 6,12-Dialkoxy- And 6,12-Dialkylsulfanyl-Benzo[1,2- b:4,5- b′]bis[ b]benzothiophenes [PDF]

, 2019
The effect of varying the chain length on the solid state conformation and packing of 6,12-dialkoxy- and 6,12-dialkylsulfanyl-benzo[1,2-b:4,5-b′]bis[b]benzothiophenes has been studied. The compounds were prepared by SNAr reaction of 6,12-difluorbenzo[1,2-

Mild N‑Arylation of Sulfoximines With (Hetero)aryl Chlorides Enabled by α‐Methylnaphthyl‐tBuBrettPhos Palladium Triflate

Chemistry – A European Journal, EarlyView.
A readily accessible, air‐ and moisture‐stable palladium precatalyst, [Pd(1‐MeNAP)(tBuBrettPhos)]OTf, enables the direct N‐arylation of NH‐sulfoximines with (hetero)aryl chlorides under exceptionally mild conditions ideal for late‐stage diversification of drug‐like scaffolds.

Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

European Journal of Inorganic Chemistry, EarlyView.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Palladium-catalyzed difluoromethylation of heteroaryl chlorides, bromides and iodides. [PDF]

, 2017
A palladium-catalyzed difluoromethylation of a series of heteroaryl chlorides, bromides and iodides under mild conditions is described. A wide range of heteroaryl halides such as pyridyl, pyrimidyl, pyrazyl, funanyl, thienyl, pyazolyl, imidazolyl ...

Biotransformation of benzothiophene by isopropylbenzene-degrading bacteria [PDF]

Journal of Bacteriology, 1994
Isopropylbenzene-degrading bacteria, including Pseudomonas putida RE204, transform benzothiophene to a mixture of compounds. Induced strain RE204 and a number of its Tn5 mutant derivatives were used to accumulate these compounds and their precursors from benzothiophene.

Preparation of 4,7‐Dihalobenzo[b]Thiophene Derivatives Containing Iodine Atoms and Their Cross Coupling With Arylethynes

Journal of Heterocyclic Chemistry, EarlyView.
Quasi T‐shaped three‐way benzo[b]thiophene scaffolds, containing iodine atom(s) at the 4‐ and/or 7‐position, were prepared by several methods such as silica gel‐assisted cyclization. The iodobenzo[b]thiophenes thus prepared were subjected to Sonogashira cross couplings to give various ethynylbenzo[b]thiophenes.

Synthesis, Characterization of Novel Benzothiophene

International Journal of Scientific Research in Science and Technology, 2021
A library of novel benzo[b] thiophenehave been synthesized regioselectively in good yields through the one-pot domino reactions of thiophenone, malononitrile and aromatic aldehydes in the presence of NaOEt. This transformation presumably involves Knoevenagel condensation–Michael addition–intramolecular Thorpe-Ziegler cyclization-Tautomerization ...
