A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 80945-86-4, Name is 6-Bromo-2-chlorobenzothiazole, molecular formula is C7H3BrClNS. In a Article£¬once mentioned of 80945-86-4, Formula: C7H3BrClNS

Tin-free, photoinduced electron transfer promoted reductive radical cyclization reactions of allyl 2-bromoaryl ethers in the presence of NaOH in 2-PrOH were found to take place efficiently to give 3-methyl-2,3- dihydrobenzofurans. In contrast to conventional radical cyclization reactions that employ AIBN/Bu3SnH in benzene, the new method utilizes NaOH and 2-PrOH that are both readily available and benign. Consequently, the newly developed photochemical process serves as a versatile and environmentally friendly method for carrying out aryl radical cyclization reactions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Formula: C7H3BrClNS, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 80945-86-4, in my other articles.

Cerebral malaria is a serious and sometimes fatal disease caused by a Plasmodium falciparum parasite that infects a female anopheles mosquito which feeds on humans. The parasites responsible for mosquito-borne infectious diseases are increasingly resistant to current drug approaches, and almost half of the world is at risk of contracting an illness. A series of twenty five new ether and ester derivatives of dihydroartemisinin (DHA) have been prepared based on in silico studies and in vitro antimalarial activity and later assessed against the chloroquine sensitive NF-54 strain of Plasmodium falciparum. In general the incorporation of nitro functionality in ester derivatives enhances the activity relative to artemisinin. Most of the ether derivatives were found to be as active as DHA, while 11-OH ether derivatives were not as active as DHA. The most potent analogue in the series was compound 21 which was several fold more active than artemisinin against P. falciparum used in the study. Molecular docking and ADMET studies were performed to explore the possible mode of interaction of active compounds in to the binding site pocket of malaria parasite target enzyme plasmepsin-II and evaluated compliance with oral bioavailability and pharmacokinetics parameters. The ester derivatives 19 and 20 were found to be twice active than DHA, having nitro functionality showing IC50 10.58 nM and 8.54 nM respectively.

Two independent enzymatic strategies have been developed toward the synthesis of enantioenriched 1-[2-bromo(het)aryloxy]propan-2-amines. With that purpose a series of racemic amines and prochiral ketones have been synthesized from commercially available 2-bromophenols or brominated pyridine derivatives bearing different pattern substitutions in the aromatic ring. Biotransamination experiments have been studied using ketones as starting materials, yielding both the (R)- and (S)-amine enantiomers with high selectivity (91-99% ee) depending on the transaminase source. In a complementary approach, the classical kinetic resolutions of the racemic amines have been investigated using Candida antarctica lipase type B as biocatalyst. Ethyl methoxyacetate was found as a suitable acyl donor leading to the corresponding (S)-amines (90-99% ee) and (R)-amides (88-99% ee) with high selectivity in most of the cases. A preparative biotransamination process has been developed for the synthesis of (2S)-1-(6-bromo-2,3-difluorophenoxy)propan-2-amine in 61% isolated yield after 24 h, a valuable precursor of the antimicrobial agent Levofloxacin.

A copper-mediated difluoromethylenation of o-bromophenols with trifluoromethanethiolate is described. This one-pot protocol proceeds through an intermolecular addition of S=CF2 (resulting from the decomposition of trifluoromethanethiolate) to o-bromophenols followed by intramolecular C-S coupling to form 2,2-difluoro-1,3-benzoxathioles. This method is compatible with a broad range of substrates and enables the late-stage difluoromethylenation of several functionally dense druglike o-bromophenols.

This study evaluates the potential of silicone rubber passive sampling devices (SR-PSDs) as a suitable alternative to automatic water samplers (autosamplers) for the preliminary identification of a wide range of organic contaminants in freshwater systems. The field performance of SR-PSDs deployed at three sites on two streams of an agricultural catchment area in North East (NE) Scotland, United Kingdom (UK) was assessed concurrently with composite water samples collected from two of the sites using autosamplers. The analytical suite consisted of selected plant protection products (PPPs; commonly referred to collectively as ‘pesticides’), including 47 pesticides and a separate sub-category of 22 acid/urea herbicides. Of these, a total of 54 substances, comprising 46 pesticides and 8 urea herbicides were detected in at least one of the SR samplers. All but 6 of these SR-PSD detected substances were quantifiable. By comparison, a total of 25 substances comprising 3 pesticides and 22 acid/urea herbicides were detected in the composite water samples, of which only 8 acid/urea herbicides were quantifiable. The larger number and chemical classes of compounds detected and quantified via passive sampling reflect the lower limits of detection achieved by this device when compared to autosamplers. The determination of dissolved concentrations of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) added to the information on contaminant pressures at each site, allowing assessment of the reliability of SR-PSDs in freshwater systems and the identification of possible contaminant sources. The study demonstrated the utility of SR-PSDs for detecting and semi-quantifying low concentrations of analytes, including those which hitherto have not been measured in the catchment area and also some pesticides that are no longer approved for agricultural use in the UK and EU. The SR-PSD approach can thus provide a better understanding and clearer picture of the use and presence of organic contaminants within catchments.
