A mechanistic study of the acid and base catalysed reactions of thiourea, 1-substituted thioureas and 1,3 -disubstituted thioureas with 1,2-diketones
(University of St Andrews, 1989) - Thesis
Thiourea, 1-substituted thioureas and 1,3-disubstituted thioureas react under acidic or basic catalysis with 1,2-diketones to give a wide variety of products. The nature of the product or products depends on the conditions ...
Some studies of the chemical reactivity of β-lactam antibiotics
(University of St Andrews, 1981) - Thesis
Rate coefficients for the inactivation of several penicillin in acids and alkalis at 30°C have been determined by means of ultraviolet spectroscopy. The case of benzylpenicillin, though well investigated in the past, has ...

(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 ...
