The formulae and structures of some aromatic amine and hydrocarbon complexes of antimony trichlorine
(University of St Andrews, 1970) - ThesisThe crystal structure of the complex 2SbCl₃.p-xylene (space group: P2₁/c; a=9.13Å, b=8.44Å, c=12.79A, β=125°21') was investigated at low temperatures, and it proves to be a layer structure with packing p-xylene molecules. ... -
Studies in the pyrolysis of some benzyl bromides
(University of St Andrews, 1961) - ThesisThe work described in subsequent pages arose from certain difficulties in the current knowledge of the bond dissociation energies (D) of compounds of the type C₆H₅CH₂-X. For the reaction C₆H₅CH₂-X → C₆H₅CH₂ - + X – D ... -
Some dihydrodiazapepinium salts and related compounds.
(University of St Andrews, 1978) - ThesisA wide variety of 6-aryl-2, 3-dihydro-1, 4-diazepinium salts has been prepared by reaction of 1,2-diamines with 1, 5-diaza-3- aryl-pentadienium salts. The latter compounds were readily accessible by Vilsmeier formylation ... -

The reactions of thiophens and furans with 2,4-dinitrobenzene diazonium compounds
(University of St Andrews, 1976) - ThesisThe reaction of several thiophens and furans with 2, 4-dinitrobenzene diazonium sulphate in glacial acetic acid/water mixture has been studied. Thiophen and its 2-and 3-monomethyl derivatives gave arylated products with ...
