    Exploration of alpha,alpha-dibromo-beta-dicarbonyl compounds as novel organic oxidants for the mild Cu(I)-catalyzed Glaser-type homo-coupling reaction has been achieved, which provides an alternatively efficient pathway for the construction of 1,3-conjugated structures. In addition, the mechanism of this reaction was investigated. (C) 2013 Elsevier Ltd. All rights reserved.

    日期:2004.6
    N,N-Dibromobenzenesulfonamide(dibromoamine-B), which is prepared easily in high yield, has been. employed as effective brominating agent for carbanionic substrates under mild conditions. beta-Diketones and beta-ketoesters were brominated by this reagent without using any bases. The reagent can be recovered, rebrominated, and reused several times.
  • α-substituted boron difluoride acetylacetonates
    作者:I. V. Svistunova、E. V. Fedorenko
    DOI:10.1134/s1070363208080094
    日期:2008.8
    By treatment of a-substituted acetylacetone derivatives with boron trifluoride etherate a series of earlier unknown boron difluoride complexes is obtained. The series includes binuclear complexes containing boron in the chelate fragment connected via sulfur or selenium atom. Gas chromatographic and spectral characteristics of the obtained compounds were investigated. By means of chromato-mass spectrometry their reaction with hydrazine in acidic and alkaline media was studied.
