The complex [NiL2] has been synthesised by the electrochemical oxidation of nickel in an acetonitrile solution of [(4-methylphenyl)sulfonyl]-imino-1H-pyridine (HL). When the oxidation was carried out in the presence of neutral ligands L′ (pyridine, 2,2′-bipyridine or 1,10-phenanthroline) the c...

Trametes versicolor U97 isolated from nature degraded 73% of the 1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane (DDT) in a malt extract liquid medium after a 40-d incubation period. This paper presents a kinetic study of microbial growth using the Monod equation. T. versicolor U97 degraded DDT d...

When treated with lithium diisopropylamide in tetrahydrofuran at −85 °C and subsequently with iodine, 2-chloro-6-(trifluoromethyl)pyridine is neatly converted into its 3-iodo derivative. The latter can be quantitatively isomerized to afford 2-chloro-4-iodo-6-(trifluoromethyl)pyridine. Either io...

The localization of HOMO, LUMO plots in the title compound over the title molecule shows the charge tr...

Antimicrobial active 5-[(4-nitrophenyl)acetamido]-2-(4-tert-butylphenyl)benzoxazole (NATPB) was synthesized and observed IR, Raman bands are compared with the theoretically predicted wave numbers. In the IR spectrum the NH stretching wave number splits into a doublet with a noted difference and ...

The title compound, first example of a stable diarylnitroxyl with vacant para-position, was best synthesized by CuCl-assisted coupling of o-tert-butylnitrosobenzene and p-tert-butylphenylboronic acid followed by N-xidation of the thus obtained unsymmetrical diarylamine. ESR investigation showed ...

The molecular structure of 9,10-bis[bis(4-tert-butylphenyl)methylene)-9,10-dihydroanthracene, an anthraquinodimethane derivative having four aryl groups on exocyclic methylene positions, was experimentally and theoretically characterized. Single-crystal diffraction study revealed that the title ...

Palladium-catalyzed coupling of arylamines and 2-bromo-3,3,3-trifluoropropene (BTP) was investigated. When a toluene solution of aniline and BTP was heated at 110 °C in the presence of Pd2(dba)3·CHCl3, 1,1′-diphenylphosphinoferrocene and Cs2CO3 under an argon atmosphere, N-(1,1,1-trifluoro-2-...

Three series of 8-trifluoromethylquinoline based 1,2,3-triazoles derivatives (5a–c, 6a–d and 7a–c) were synthesized by multi-step reactions by click chemistry approach. Synthesized compounds were characterized by spectral studies and X-ray analysis. The final compounds were screened for their...

A variety of degradation products are produced upon dilute acid pretreatment of lignocellulosic biomass. Within this larger construct, organic acids, phenols and aromatic aldehydes represent important compound classes to investigate due to increasing evidence of their inhibitory effect on fermen...

Carbon-carbon coupling play a vital role in the synthetic field of organic chemistry. Two novel pyridine derivatives: 3-bromo-5-(2,5-difluorophenyl)pyridine (1) and 3,5-bis(naphthalen-1-yl)pyridine (2) were synthesized via carbon-carbon coupling, characterized by XRD, spectroscopic techniques an...

Glycosyl phenylthiosulfonates are reagents which are valuable for the S-glycosylation decoration of organic compounds and proteins. Here, one-pot multiple-component synthesis of glycosyl phenylthiosulfonates from sulfinate, sulfur powder and glycosyl bromides is reported. The reactions afford gl...

A series of 2-substituted 4-(trifluoromethyl)benzyl C-region analogs of 2-(3-fluoro-4-methylsulfonamidophenyl)propanamides were investigated for hTRPV1 antagonism. The analysis indicated that the phenyl C-region derivatives exhibited better antagonism than those of the corresponding pyridine sur...

A high-throughput screening campaign helped us to identify an initial lead compound (1) as a protein kinase C-θ (PKCθ) inhibitor. Using the docking model of compound 1 bound to PKCθ as a model, structure-based drug design was employed and two regions were identified that could be explored for...

A synthetic route for 1,4-dimethyl-6-phenylfulvene (4) and 1,4-dimethyl-6,6-diphenylfulvene (5), which are characteristic in that they have substituents only on 1-, 4-, and 6-positions, is developed.
