Chlorothiophenols (CTPs) and chlorophenols (CPs) are key precursors for the formation of PCTA/PT/DTs, which can react with H or OH to form chloro(thio)phenoxy radical, sulfydryl/hydroxyl-substituted phenyl radicals, and (thio)phenoxyl diradicals.

Abstract:

Five novel reagents were suggested for mercury (II) photometric determination: 2hydroxythiophenol and its derivatives (HTDs), namely 2,5-dihydroxythiophenol, 2-hydroxy-5fluorothiophenol, 2-hydroxy-5-chlorothiophenol, 2-hydroxy-5 - bromothiophenol, 2- hydroxy – 5- iodothiophenol. The molar absorptivity coefficient was (2.4-3.3)×104 (λ=450-480 nm). The optimal conditions for the complexation reaction correspond to pH range of 4.1 - 7.2. It has been proven that a compound with different ligands is formed in the ratio of Hg (II):HTDs:Py=1:2:2.

Abstract:

Silica (SiO2), accounting for the main component of fly ash, plays a vital role in the heterogeneous formation of polychlorinated thianthrenes/dibenzothiophenes (PCTA/DTs) in high-temperature industrial processes. Silica clusters, as the basic units of silica, provide reasonable models to understand the general trends of complex surface reactions. Chlorothiophenols (CTPs) are the most crucial precursors for PCTA/DT formation. By employing density functional theory, this study examined the formation of 2-chlorothiophenolate from 2-CTP adsorbed on the dehydrated silica cluster ((SiO2)3) and the

Background: Pain is often the first indication of disease or injury. Analgesics are the drugs used clinically for controlling pain. They relieve pain as a symptom, without affecting its cause. Currently available options are nonsteroidal anti-inflammatory drugs (NSAIDs) and opioid analgesics for the management of pain. Long term use of existing analgesics causes significant disturbances in the body system. A search for new, safe and cost effective analgesic compound is in progress.

Abstract:

The asymmetric unit of the title compound, 2C5H3ClO2S·C10H8N2, is comprised of a molecule of 3-chlorothiophene-2-carboxylic acid (3TPC) and half of a molecule of 4,4′-bipyridine (BPY). A distinctive O—H...N-based synthon is present. Cl...Cl and π–π stacking interactions further stabilize the crystal structure, forming a two-dimensional network parallel to thebcplane.

Abstract:

The regioselective ipso-formylation of electron-rich, 3,4-push-pull-substituted 2-chlorothiophenes under Vilsmeier-Haack conditions was performed in good yields. The synthetic scope of this new reaction was explored using various halothiophenes, chloroanilines, and 1-methyl-3-chloroindole. In comparison with their structural C-H analogs the chlorinated thiophenes, anilines, and the indole proved to be less reactive toward electrophilic attack by chloromethyleniminium salts.

Abstract:

Stable crystalline 2-chlorothiophene has two glass transitions at 164 and 186 K. 35CI NQR measurements were carried out between 77 and 200 K. Two NQR signals with full widths of about 100 kHz at half maximum were observed in this temperature range. The spin-lattice relaxation times T1 were measured at the two peak frequencies. The activation energy obtained from the results of the T1 measurements showed a fairly good agreement with those estimated from calorimetric measurements.

Abstract:

Present work illustrates the stress degradation behaviour of rivaroxaban under hydrolytic, oxidative, thermal and photolytic conditions as per ICH guidelines. Under thermal and photolytic conditions drug had a fair stability where as in other stress conditions degradation products were observed. Initial identification of the degradation products was performed by hyphenated mass spectrometry coupled to ultra-performance liquid chromatography (UPLC-MS) and mass directed auto purification (MDAP) was used for isolation. Various 1D and 2D nuclear magnetic resonance (NMR) were performed to character

Abstract:

Fiesselmann thiophene synthesis was applied for the convenient construction of thieno[3,2-b]thiophene derivatives. Thus, new 5- or 6-aryl-3-hydroxythieno[3,2-b]thiophene-2-carboxylates were obtained by condensation of 5- or 4-aryl-3-chlorothiophene-2-carboxylates, respectively, with methyl thioglycolate in the presence of potassium tert-butoxide. The saponification of the resulting esters, with decarboxylation of the intermediating acids, gave the corresponding thieno[3,2-b]thiophen-3(2H)-ones. The latter ketones were used to synthesize new N,S-heterotetracenes, namely 9H-thieno[2',3':4,5]thie
