    • Some electrophilic reactions of pyrrole and related compounds 

      Alexander, Robert Scott (University of St Andrews, 1977) - Thesis
      Chapter One describes the mechanism of acid-catalysed hydrogen-exchange in methylpyrroles. Using buffer solutions it was found that this reaction is subject to general acid catalysis, confirming an A-S[sub]E2 mechanism. ...

    • Preparation and pyrolysis of some sulphinyl-stabilised phosphorus ylides 

      Ryan, Bruce Martin (University of St Andrews, 1996) - Thesis
      The results of further investigation into the pyrolytic behaviour of alkane- and arenesulphinyl alkoxycarbonyltriphenylphosphoranes are reported. Flash vacuum pyrolysis (FVP) of these ylides at 600°C gives vinyl sulphides, ...

    • Studies in organophosphorus chemistry 

      Maynard, Judith Ann (University of St Andrews, 1966) - Thesis
      Various methods of alkylation of the >PO₂⁻,>-PS₂⁻ and >POS⁻ ions have been investigated. Ethyl miethylphosphonate reacted with 2-methyloxiran to give ethyl 2-hydroxypropyl methylphosphonate and with p-nitrobenaonitrile ...

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

      Todd, Michael James (University of St Andrews, 1967) - Thesis
      As a synthetic procedure, the deoxygenation of aromatic nitro-compounds by tervalent organophosphorus compounds has been extended to include new routes to the anthranil and phenothiazine nuclei. Synthesis of anthranils ...

    • N-Nitrosoacylarylamines 

      Thomson, Jemima Birrell (University of St Andrews, 1968) - Thesis
      The decompositions of N-nitrosoacylarylamines in benzene and in carbon tetrachloride have been investigated. The reaction products of N-nitrosobenzanilldes parallel those of N-nitrosoacetanilides, carboxylic acids being ...
