    Kinetics and mechanism of benzyl chloride reaction with zinc in dimethylacetamide
    摘要:
    Oxidative dissolution of zinc in the system of benzyl chloride-dimethylacetamide was investigated. The reaction stereochemistry as well as intermediates and reaction products formed were studied. The kinetic and thermodynamic parameters of the process were measured. The process was shown to follow the Langmuir-Hinshelwood mechanism with the formation of benzyl radicals and mono-solvated organozinc compound on the zinc surface. The components of mixture are adsorbed at various sites of the zinc surface, while recombination and the isomerization of the benzyl radicals occurs in solution.

    日期:2021.4.22
    An oxoammonium‐mediated α‐C(sp3) allylation of allyl‐ and benzyl ethers using allylsilanes as nucleophilic partners is disclosed. This new C−C bond forming C−H activation process allows to obtain the corresponding coupled products in moderate to good yields.

    produces alkyl-Tempo in very good yield. Good results are also obtained with FeII-H2O2 system (pyridine, Picolinic Acid, hydrocarbon). In this case the FeII-FeIV manifold is responsible for the formation of the adduct. Using FeIII-H2O2, Tempo adduct is formed at the same rate as the oxidation products. Mechanistic studies suggest the oxidation of Tempo by the FeV to give an oxoamonium salt and an FeIV species

  • Thermal decay of TEMPO in acidic media via an N-oxoammonium salt intermediate
    作者:Yun Ma、Colin Loyns、Peter Price、Victor Chechik
    DOI:10.1039/c1ob05475a
    日期:——
    Disproportionation of TEMPO in acids leads to the formation of an N-oxoammonium salt, which can further decompose under thermal conditions, yielding the corresponding hydroxylamine, N2O, CO2 and a series of dimerisation products. Overall, acid-catalysed thermal decay of TEMPO leads to ca. 80% yield of hydroxylamine.

    作者:Kengo Akagawa、Kazuaki Kudo
    DOI:10.1021/ol2012956
    日期:2011.7.1
    An asymmetric α-oxyamination could be successfully performed by a peptide catalyst and laccase. The combination of peptide catalysis and enzymatic air oxidation promoted the reaction smoothly in water without employing a metal reagent. The oxyaminated compounds could be obtained as both aldehyde and carboxylic acid products depending on the reaction conditions.

    A process for the recovery of an organic nitroxy compound from a solution of this nitroxy compound in an organic solvent or a mixture of a water-miscible organic solvent and water, the process includes the steps of: (a) adjusting the pH of the solution to a value below 4 to generate a nitrosonium ion and the -protonated hydroxylamine; (b) removing the organic solvent until a residue containing the nitrosonium ion and the protonated hydroxylamine has formed; (c) if necessary, redissolving the residue obtained in water; and (d) neutralizing the resulting aqueous solution to recover the nitroxy compound.
