    • Some new reactions and some new syntheses of long-chain unsaturated acids 

      Hussain, Mohammad Golbar (University of St Andrews, 1973) - Thesis
      Part I. The preparation and reactions of long-chain acids containing sulphur. Much is known about long-chain hydroxy esters and the epoxides which can be derived from them but information about the corresponding sulphur ...

    • The reactivity of some organophosphorus esters 

      Eastlick, David Thomas (University of St Andrews, 1969) - Thesis
      Part 1: The occurrence of bimolecular nucleophilic aromatic substitution has been established in the reaction of o-dinitrobenzene with triethyl phosphite and diethyl methylphosphonite in acetonitrile solution. There is a ...

    • Studies of some aliphatic constituents of shellac 

      Prentice, Hugh Graham (University of St Andrews, 1962) - Thesis
      Hydrolysis of lac resin yields a mixture of acids among which only two - aleuritic (up to 40%) and shellolio (up to 5%) - have been adequately characterised and examined by several investigators. The work embodied in this ...

    • Generation and reactivity of carbon, sulphur and tellurium centred free radicals 

      Culshaw, Peter Norman (University of St Andrews, 1991) - Thesis
      Using ESR dimer-radical equilibrium techniques the heat of formation, △Hf⁰, of the pentamethylcyclopentadienyl radical was determined as 7.4 kcal mol⁻¹, and hence SEMeH was calculated to be 37.9 kcal mol⁻¹. It was attempted ...

    • Catalysis in the hydrolysis of esters and related compounds 

      Robertson, Ian (University of St Andrews, 1975) - Thesis
      The first chapter is concerned with an investigation into the kinetics and mechanism of the base-catalysed hydrolysis of some substituted phenyl chloroformates. A study of kinetic isotope effects and activation parameters ...
