The sp3-C-H peroxidation of 3,4-dihydro-1,4-benzoxazin-2-ones was achieved under mild and simple catalyst-free reaction conditions. A range of biologically important alkylated benzoxazinone peroxides are synthesized in high yield with a good functional group tolerance. The C(sp3)-OO bond was constructed efficiently and could be further converted into C(sp3)-C(sp3), C(sp3)-C(sp2), C(sp3)-C(sp), C-P and CO bonds by late-stage functional group transformations.

Polychloroazines (1-6) are susceptible to homolytic chlorine substitution by alkyl radicals.In general, the chlorine at the ortho-position to the ring nitrogen is readily replaced by an alkyl radical like adamantyl and tert-butyl.However, the chlorine at the C2-position of pyrimidine did not show any sign of the radical substitution.The reactivity decreases in the order of adamantyl, tert-butyl, and isopropyl radicals.

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 2213-63-0 is helpful to your research. Application of 2213-63-0

The synthesis of quinoxaline P,N ligands by monoamination of 2,3-dichloroquinoxaline (1) to 2-amino-3-chloroquinoxalines 2a,b and the subsequent substitution of chlorine by a diphenylphosphanyl group was studied. Whereas the reaction of 2a,b with Ph2PH in the presence (or absence) of catalytic amounts of palladium acetate furnished only minor amounts of the expected ligands in favor of tetraphenyldiphosphane and dechlorinated quinoxalines, the coupling with Ph2PLi in ether provided the novel NH-functional P,N hybrid ligands 3a,b with a quinoxaline scaffold in moderate to good yields. 3a is slightly and 3b somewhat more sensitive to air oxidation, leading to the P-oxides 4a,b. The more reactive 1 forms with Ph2PH only a small amount of 2-chloro-3-diphenylphosphanylquinoxaline 5 and traces of the quinoxaline-bis(phosphane) 6. The main products are 2,2?- bis(quinoxaline) and Ph2PCl, which converts residual Ph2PH into tetraphenyldiphosphane. The coupling with Ph2PLi in diethyl ether, however, gave in a fast reaction high yields of 6, exceeding those of 3a,b, with interfering NH functions. Semi-empirical quantum chemical calculations (PM6) illuminate the background of the air sensitivity of 3a,b, whereas the recently reported 6 is air stable. Preliminary studies for use of the ligands in catalysis with the air-stable 6, showed moderate to good yields in the Pd-catalyzed C-N cross coupling of 2-bromopyridine with mesityl amine. Complex formation was confirmed by isolation of the Pd complex 7. The structure elucidation of the new compounds is based on conclusive NMR data and crystal structure analyses for 2b, 3a, 4a and 4b.

1448-87-9, Name is 2-Chloroquinoxaline, belongs to quinoxaline compound, is a common compound. Quality Control of 2-ChloroquinoxalineIn an article, once mentioned the new application about 1448-87-9.

Simple iron salts such as FeCln, Fe(acac)n (n = 2,3) or the salen complex 4 turned out to be highly efficient, cheap, toxicologically benign, and environmentally friendly precatalysts for a host of cross-coupling reactions of alkyl or aryl Grignard reagents, zincates, or organomanganese species with aryl and heteroaryl chlorides, triflates, and even tosylates. An “inorganic Grignard reagent” of the formal composition [Fe(MgX)2] prepared in situ likely constitutes the propagating species responsible for the catalytic turnover, which occurs in many cases at an unprecedented rate even at or below room temperature. Because of the exceptionally mild reaction conditions, a series of functional groups such as esters, ethers, nitriles, sulfonates, sulfonamides, thioethers, acetals, alkynes, and -CF3 groups are compatible. The method also allows for consecutive cross-coupling processes in one pot, as exemplified by the efficient preparation of compound 12, and has been applied to the first synthesis of the cytotoxic marine natural product montipyridine 8. In contrast to the clean reaction of (hetero)aryl chlorides, the corresponding bromides and iodides are prone to a reduction of their C-X bonds in the presence of the iron catalyst.
