The title compound, C(17)H(15)BrOS, was prepared by the Lewis acid-catalysed reaction of 2,4-dimethyl-phenol with 4'-bromo-2-chloro-2-(methyl-sulfan-yl)acetophenone. The 4-bromo-phenyl ring is rotated slightly out of the benzofuran plane, making a dihedral angle of 8.4 (1)°. The crystal structure is stabilized by a CH(2)-H⋯π inter-action between the 5-methyl group and the benzene ring of the be...

1-(3-(Pyridin-2-yl)phenyl)methanamine derivatives have been synthesized and underwent C–H bond activation to afford unsymmetrical NCN’ pincer palladacycles, which were characterised in the solid state. 2-Pyridinyl-phenol and -benzyl alcohols were then used as precursors to unsymmetrical PCN pincer palladacycles. Catalytic applications, where the palladacycle remains in the Pd(II) state, have be...

Wood processing in Indonesia produces a lot of sawdust waste that has not been fully utilized. One way to overcome this is process it into liquid smoke which can be used as raw material for fish preservatives. The began with pyrolising the smoke, was then purified by distillation, and results were characterized GCMS FTIR. Liquid quality testing also carried out, namely measuring pH, determining...

ion via reaction (647) is dominant, due to its low activation energy, up to 0.4 cm above the burner while reaction (644) becomes dominant farther from the burner. Reaction with OH to give phenol, i.e., reaction (652), does not contribute significantly to benzene depletion while the reverse reaction even leads to benzene formation close to the burner. Benzene formation in the acetylene flame res...

Arsenic trioxide has shown the excellent therapeutic efficiency for acute promyelocytic leukemia. Nowadays, more and more research focuses on the design of the arsenic drugs, especially organic arsenicals, and on the mechanism of the inducing cell death. Here we have synthesized some organic arsenicals with Schiff base structure, which showed a better antitumor activity for three different kind...

The site-selective H/D exchange reaction of phenol in sub-and supercritical water is studied without added catalysts. In subcritical water in equilibrium with steam at 210–240 °C, the H/D exchange proceeds both at the ortho and para sites in the phenyl ring, with no exchange observed at the meta site. The pseudo-first-order rate constants are of the order of 10 Ϫ4 s Ϫ1 ; 50% larger for the orth...

The Raderecht and Moskau procedure for pancreatic lipase (6) has been modified for determining the small amounts of this enzyme present in normal blood serum. The present investigation confirmed their findings: that phenyl laurate provides a stable easily-prepared substrate of uniform composition; that the substrate is specifically split by serum and pancreatic lipase; and that the reaction pro...

Phenols are present in the environment and commonly in contact with humans and animals because of their wide applications in many industries. In a previous study, we reported that uridine diphosphate-glucose-dependent glucosyltransferase PtUGT72B1 from Populus trichocarpa has high activity in detoxifying trichlorophenol by conjugating glucose. In this study, more experiments were performed to d...

Large-scale screening of enzyme libraries is essential for the development of cost-effective biological processes, which will be indispensable for the production of sustainable biobased chemicals. Here, we introduce a genetic circuit termed the Genetic Enzyme Screening System that is highly useful for high-throughput enzyme screening from diverse microbial metagenomes. The circuit consists of t...

This study examines the pyrolysis products of smoked methamphetamine mixed with tobacco that was trapped with a C8 adsorbent cartridge and then detected by gas chromatography-tandem mass spectrometry. According to the results, the mainstream smoke contains 2-methylpropyl-benzene, 2-chloropropyl-benzene, 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one, 3-ethyl-phenol, methamphetamine, dimethyl...
