    • Some new heterocyclic thermosets 

      Nicolson, Neil James (University of St Andrews, 1996) - Thesis
      The original aim of this project was to investigate the possibility of synthesising a novel polymer system combining the best features of cyanate ester resins and epoxy resins. Chapter 1 presents the historical background ...

    • Novel derivatives of DPP and related heterocycles 

      Morton, Colin J. H. (University of St Andrews, 1999) - Thesis
      This thesis discusses the synthesis of new organic, heterocyclic materials for potential application as pigments. Chapter 1 comprises an introduction to the field of pigment and dye chemistry, discussing the rudimentary ...

    • Some aspects of the molecular structure of heterocyclic and organometallic compounds 

      Cutherbertson, Alastair Fraser (University of St Andrews, 1983) - Thesis
      Various rules which have been used to rationalise molecular geometries are discussed. After this the results from MNDO calculations on simple carbenes, ethers and amines are presented, and these were designed to test the ...

    • Cyclopentadienylides 

      Freeman, Brian Harding (University of St Andrews, 1971) - Thesis
      The thermal decomposition of 2,3,4,5-tetraphenyldiazocyclopentadiene in the presence of carbene acceptors having Group V and VI elements to give 2,3,4,5-tetraphenylcyclopentadienylides has been extended and the first example ...

    • Studies in the perinaphthene series 

      Sutherland, Ronald George (University of St Andrews, 1962) - Thesis
      The thesis comprises three parts, A, B and C. Each part is divided into a number of principle sections which are prefixed by Roman numerals. Most sections are divided into subsections prefixed by Roman numerals. Part A ...
