Streszczenie:

This thesis explores the synthesis and conformational behaviour of hexahydropyrimidines and related heterocycles, with particular emphasis on 5- hyrdohexahydropyrimidines. The conformational behaviour of these compounds was investigated using dynamic NMR spectroscopy, molecular modelling techniques and X-ray crystal structure analysis. The conformational behaviour of 5- hyrdohexahydropyrimidine, hexahydropyrimidine and their analogous oxygen compounds as well as a series of hexahydropyrimidines with various exocyclic substituents, were examined. The preferred conformations of all these compoun

Streszczenie:

The potential use of electron-deficient heterocyclic azo compounds as inkjet dyes was explored. 2-Nitrosopyridine could be used to form a series of azo compounds via the Mills’ reaction with electron-rich aromatic amines. Conditions for this process were optimised by varying solvent and pH. In the presence of ethers, 2-nitrosopyridine is quickly reduced to azoxypyridine. This reaction follows first order kinetics; diethyl and diisopropyl ether react at similar rates, whereas cyclic ethers such as THF are far slower. Organic bases such as Hunigs base were also found to promote formation of azox

Tetrazolinones, thiatriazole 1-oxides and meso-ionic oxatriazoles were investigated as sources of free radicals. Mono-substituted tetrazolinones decomposed at their melting points. Nitrosation and nitration of the tetrazolinone ring was unsuccessful, although alkoxyalkylation of the ring took place in ether in the presence of nitrosomium and nitronium tetrafluoroborate. The tetrazolinone ring was photolytically unstable, and both eliminated nitrogen and cycloreverted. γ-irradiation of the naphthyl deivative caused cleavage of the nitrogen-hydrogen bond to give a radical which was identified by

It is generally accepted that platinum antitumour drugs bind, preferentially, to Guanine N7 in DNA.

Six complexes of the type cis-PtCl2L2, where L is a N-heterocycle, have been successfully prepared and characterized.
