    were performed in the presence of LiBr with Pd(OAc)2 as the catalyst. Two different reoxidants, p-benzoquinone or Cu(OAc)2, were used, the choice of oxidant being dependent on the substrate. The reaction proceeds through an external nucleophilic attack (Br-) on a (π-allene)palladium complex to produce a (π-allyl)palladium intermediate. Subsequent intramolecular attack by the second internal nucleophile

    An iridium-catalyzed cycloisomerization of N-allenyl pyrroles and indoles is reported. The method, which is initiated by a C−H activation step, delivers a diversity of synthetically relevant azaheterocyclic products, depending on the precise ancillary ligand used and the substitution pattern of the allene. Particularly attractive are the hydrocarbonation cascades of tetrasubstituted allenyl precursors

  • Dimethyldioxirane oxidation of primary amines
    作者:Jack K. Crandall、Thierry Reix
    DOI:10.1021/jo00051a017
    日期:1992.12
    Several primary amines 2 have been oxidized with dimethyldioxirane (1) under a variety of conditions. Mixtures of dimeric nitrosoalkanes 4 and oximes 5 were typically obtained with solutions of the oxidant in excess. In several instances, nitrones 12 were found as byproducts in these reactions. In situ oxidations using oxone in buffered aqueous acetone solution also gave nitrosoalkanes 4 and oximes 3 as important products; in addition, oxaziridines 11 were obtained in significant amounts in biphasic procedures containing methylene chloride. The corresponding nitroalkanes 3 were not formed in major amounts in either oxidation procedure, unless large excesses of oxidant were used. These results are discussed in terms of the several competing processes which occur under the different reaction conditions.
