    • The reactions of tervalent phosphorus reagents with aromatic nitro-compounds 

      Sears, David John (University of St Andrews, 1968) - Thesis
      The reactions of tervalent phosphorus reagents with a number of aromatic nitro-compounds have been investigated. While it was expected that such reactions would give further examples of the deoxygenation and further reaction ...

    • E.S.R. studies of the decomposition of acylarylnitrosamines 

      Paton, Robert Michael (University of St Andrews, 1969) - Thesis
      The E. S. R. spectra observed during the decomposition of acylarylnitrosamines in four series of solvents have been investigated, and the mechanisms of the reactions discussed in terms of the radicals involved. For aromatic ...

    • Studies of some condensed polyazaheteroaromatic compounds 

      Shepherd, Tom (University of St Andrews, 1984) - Thesis
      The cyanide induced cyclisation of a number of substituted 2-acetamido-N-(o-nitrobenzylidene)anilines was investigated, resulting in the formation of the appropriate unambiguously substituted quinoxalino[2,3-o]cinnolines. ...

    • Base-induced cyclisations of ortho-substituted nitro-aromatics 

      McFarlane, Michael David (University of St Andrews, 1988) - Thesis
      In Chapter I some of the chemical, biological and physical properties of purine analogues, particularly benzimidazole N-oxides, are briefly discussed. In Chapter II, the preparations of 4-, 5-, 6-, and 7-amino-1H-benzimidazole ...

    • Nitrene-induced aromatic rearrangements 

      Kulik, Stanley (University of St Andrews, 1970) - Thesis
      It has been shown in this investigation that thermal decomposition of mono-substitutedaryl 2-azidophenyl sulphides and deoxygenation of mono-substitutedaryl 2-nitrophenyl sulphides both proceed via a re-arrangement involving ...
