    • Occurence and reactions of long-chain epoxy acids 

      Conacher, Henry Brown Stewart (University of St Andrews, 1968) - Thesis
      The possibility that long-chain epoxy acids may be key intermediates in the biosynthesis of acids with conjugated unsaturation has been investigated. By isomerisation of several epoxy acids with acidic and basic catalysts ...

    • Epoxidation of unsaturated esters 

      Schuler, Hermann Robert (University of St Andrews, 1974) - Thesis
      Eight isomeric 9,12-diunsaturated c₁₈ methyl esters and seven isomers from two series of positionally isomeric methyl octadecacis, cis-dienoates, ie. 18:2 (5c12c - 8c12c) and (6c9c - 6c11c) were epoxidised to furnish ...

    • Some reactions of methyl octadecenoates and related compounds 

      Perera, Buvipali Srima (University of St Andrews, 1972) - Thesis
      Part I: The Methyl trans-Methyleneoctadecanoates. The sixteen isomeric methyl trans-methyleneoctadecanoates have been synthesised from the corresponding methyl trans alkenoates by the Simmons-Smith reaction, and some of ...

    • Internal rotation about c-c and c-n bonds 

      Hamlin, Sally-Anne (University of St Andrews, 1978) - Thesis
      A study of the historical and more recent work on rotation about carbon-carbon and carbon-nitrogen bonds was the basis for the further investigation of three series of compounds: 1. 2,2'-disubstituted biphenyls, 2. ...

    • New variations of the 1, 6, 6aλ⁴-triheterapentalene structure 

      Mitchell, James Alexander (University of St Andrews, 1979) - Thesis
      The reaction between 3-substituted-5-phenyl-1, 2-dithiolium salts and various aminoheterocycles was investigated. Substituted 2-aminopyridines gave, in most cases, a mixture of two isomeric products, formulated as ...
