    • Some hydrolytic reactions of beta-lactams 

      Freeman, Keith (University of St Andrews, 1976) - Thesis
      This thesis describes the synthesis and alkaline ring fission of some β-lactams. Three series of β-lactams were studied: those of type (A) bearing a substituent on the ring nitrogen; 1,3,4-trisubstituted 3-lactams (B); and ...

    • Studies in polymer alloys for applications in prosthetics 

      Smith, John Storrar Gunn (University of St Andrews, 1996-07) - Thesis
      This study relates to the preparation of polymer composites with properties of interest in dental and medical fields. These applications concern, bone cements which are used in total hip replacement operations, tooth filler ...

    • Reactive intermediates in the reactions of aryl halides with bases 

      Hall, Julia Kathleen Aylmer (University of St Andrews, 1969) - Thesis
      The reaction of a series of 2,6-dimethylaryl halides with strong base has been investigated. Debromination to give polymethylbenzenes has been found to occur in all the systems studied and varying amounts of higher-boiling ...

    • The chemistry of glucosone 

      Fewster, John A. (University of St Andrews, 1953) - Thesis
      Although the osones were first prepared by Emil Fischer sixty-five years ago and, in the intervening period, investigation of these compounds has not been neglected, there exists no modern comprehensive review of their ...

    • Some reactions of urea and related compounds 

      Hussain, Ishtiaq (University of St Andrews, 1980) - Thesis
      In this thesis reactions of urea and its N-alkyl derivatives with monoketones, α-diketone s, enzladehyde, acyloins, diaminoethane and its N-alkyl derivatives, oxidation of alkyl and aryl derivatives of thiourea, nitration ...
