The anion of 2-aryl acetonitrile derivatives reacted with a variety of heteroaryl chlorides or bromides in an SNAr manifold to afford intermediate anions which were susceptible to oxidation. The addition of sodium peroxide and aqueous NH4OAc solution effected oxidation to afford aryl heteroaryl ketones in good yields. Aryl acetonitrile derivatives are thus umpolung-type synthons of the corresponding aryl carbonyl functionality.

Focused microwave irradiation of a series of halogenated nitrogen heterocycles and different kinds of nucleophiles in the presence of a catalytic amount of indium trichloride leads to the efficient and completely regioselective generation of aromatic C-C and C-N bonds. The method is simple, rapid, general and inexpensive, and can be performed without the use of dried solvents. Most of the synthetized compounds are new and in many cases the work-up required only filtration. Furthermore, this is the first example of the use of a Lewis acid as a catalyst for heteroarylation, vinylation and amination reactions on pi-deficient heterocyclic substrates.

New Advances in Chemical Research, May 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Reference of 1448-87-9, In a article, mentioned the application of 1448-87-9, Name is 2-Chloroquinoxaline, molecular formula is C8H5ClN2

Different substituted pyridinium N-heteroarylaminides have been prepared in one step from N-aminopyridinium iodide and the corresponding heteroaryl halide by two alternative routes. The use of Pd catalysis allowed the easy preparation of products from the less reactive haloheterocycles. The use of water as a solvent in conjunction with microwave heating dramatically diminishes the reaction time without having an adverse effect on reaction yields.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1448-87-9 is helpful to your research. Reference of 1448-87-9

The synthesis of 2-(4-nitrophenoxy)quinoxaline (3) is described. The reaction of (3) with hydroxide ion was studied in the presence and absence of micellar systems. Cationic micelles of cetyltrimethylammonium chloride and bromide (CTACl and CTABr) and tetradecyltrimethylammonium chloride and bromide (MTACl and MTABr) speed the reaction of (3) with hydroxide ion. The second-order rate constants at the micellar pseudophase are smaller than the second-order rate constant in water.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 1448-87-9, In a article, mentioned the application of 1448-87-9, Name is 2-Chloroquinoxaline, molecular formula is C8H5ClN2

Novel 1,4-diazine-based dyes of the D?pi?A type, possessing triphenylamine as an electron-donating group, have been developed. Fluorescence studies have demonstrated that emission of these fluorophores is sensitive towards different nitroaromatic compounds and aliphatic amines, both in solutions and in a vapor phase. Moreover, these compounds can be considered as ?naked-eye? fluorescent probes for solution polarity because they possess pronounced solvatochromic properties. Therefore, these compounds have to be regarded as potential multifunctional chemosensors for monitoring hazardous organic substances.

An efficient and mild protocol has been developed for the Minisci acylation reactions of nitrogen-containing heteroarenes with alpha-keto acids. Distinct from the conventional Minisci acylation conditions, the chemistry was performed using non-noble metal Fe(II), instead of expensive Ag(I) salt, as catalyst. A wide range of substrates, including aliphatic or aromatic alpha-keto acids, as well as various N-heteroarenes, proved to be compatible with the protocol. Scale-up experiment also demonstrates the practicality of the approach.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 2-Chloroquinoxaline, you can also check out more blogs about1448-87-9

Reaction of 2-chloroquinoxaline (1) with O-potassio-3,3-dimethyl-2-butanone (2) in liquid NH3 affords 1-(quinoxalin-2-yl)-3,3-dimethyl-2-butanone (3) via a thermal SRN1 mechanism and 2-tert-butylfuro<2,3-b>quinoxaline (4) via a competing ionic, addition-substitution process.When the SRN1 component of this … scheme is inhibited by di-tert-butyl nitroxide, only furoquinoxaline 4 is produced.O-Potassio-2,4-dimethyl-3-pentanone (5) reacts in a similar fashion with 1 to give SRN1 products, 2-(quinoxalin-2-yl)-2,4-dimethyl-3-pentanone (6) and 2-isopropylquinoxaline (8), along with quinoxalino<3,4-b>-2,2,5,5-tetramethylcyclopentanone (7), which results from addition-substitution.Reaction of 1 with O-potassio-3-methyl-2,4-pentanedione (9) affords low yields of 2-(quinoxalin-2-yl)butanone (10) by a sluggish SRN1 pathway.Reactions of 4-chloroquinazoline (11a) and 4-chloro-2-phenylquinazoline (11b) with enolate 2 provide excellent yields of the respective 4-quinazolinyl ketones 12a,b via an apparent SNAr mechanism.
