The electrochemical oxidation of phenols and their alkyl ethers not containing strong electron-withdrawing substituents in fluorosulfonic acid takes place in the form of the benzenonium ions and is irreversible in character.With the introduction of substituents of the -M type into the benzene ring the oxidation process affects the unprotonated molecules to a first approximation and in many cases goes reversibly to the radical-cations.Comparison of the oxidation potentials of the substrates in acetonitrile and fluorosulfonic acid made it possible to reveal certain characteristics of the fine structure of these radical-cations, which is determined by the ability of the latter to interact with the medium.Heterocyclic cations whose oxidation potentials in acetonitrile lie beyond the limit of the discharge of the supporting electrolyte can be oxidized in fluorosulfonic acid.Cations of the quinolinium, isoquinolinium, acridinium, acridizinium, imidazolium, and other series, which have irreversible many-electron waves in acetonitrile, give well-defined reversible peaks for oxidation to the corresponding radical-dications in fluorosulfonic acid.In phenyl- and benzyl-substituted cations the substituents and not the positively charged heterocycle itself can undergo oxidation.

An efficient methodology is described and exploited for the preparation of differently substituted indoles and azaindoles via microwave-assisted cycloisomerization in water of 2-alkynylanilines and alkynylpyridinamines, which is promoted by catalytic amounts of neutral or basic salts or by stoichiometric weak organic bases. Good to high yields in the cyclization can be achieved for a variety of 2-amino(hetero)aryl alkynes. Reactions are run without any added metal catalyst. A comparison with the cycloisomerization conducted under conventional heating is also described.

New Advances in Chemical Research, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.Computed Properties of C9H7ClN2, In a article, mentioned the application of 32601-86-8, Name is 2-Chloro-3-methylquinoxaline, molecular formula is C9H7ClN2

The synthesis and characterization of 14 monometallic derivatives of quinoline, quinoxaline, quinazoline and tetraazolo<1,5-A>quinoline and a bimetallic derivative of quinoxaline are reported. These species were prepared in 11 to 88% isolated yields by metathesis reactions between NaFp or NaFp? (where Fp = (eta5 – C5H5)Fe(CO)2 and Fp? = (eta5 – indenyl)Fe(CO)2 ) and the appropriate chlorine substituted polyaromatic azines. These reactions are highly regioselective and generally produce a single organometallic product having the organometallic substituent(s) bonded to the more highly activated azine ring. The structures of three representative examples were confirmed by their X-ray crystal structures, which are reported for the title complexes 4-[(eta5-cyclopentadienyl)irondicarbonyl]-7-chloroquinoline (C16H10ClFeNO2; a = 7.608(1)A, b = 12.006(1)A, c = 15.664(1)A, V = 1431A3; orthorhombic; P212121; Z =4), 2-[(eta5-cyclopentadienyl)irondicarbonyl]-3-chloroquinoxaline (C15H9ClFeN2O2; a = 15.291(3) A, b = 6.561(2) A, c = 14.541(4) A, beta = 106.891(21), V= 1395.9A3; monoclinic; P21/c; Z = 4), and 2-[(eta5-indenyl)irondicarbonyl]-3-chloroquinoxaline (C19H11ClFeN2O2; a = 19.131(2)A, b = 6.688(1)A, c = 13.515(2) A, beta= 101.569(11), V = 1694.1 A3; monoclinic; P21/c; Z = 4). The bimetallic quinoxaline derivative 2,3-[(C5H5)2Fe2(CO)4]-quinoxaline has orrto-substituted organometallic groups and the spectroscopic data suggest that it has an unusual structure in solution, perhaps involving bridging cyclopentadienyl and carbonyl ligands.
