Abstract
The work undertaken in this thesis is the photochemical rearrangement of :
Each of mono-, di-, and tribenzylamines separately in different solvents whereby benzylchloride, benzaldehyde, toluene, bibenzyl, ammonia and benzylisocyanide were formed during the photolysis of each amine in carbontetrachloride in addition to a mixture of mono-, di- and tri-benzylamines, and a solid insoluble in carbontetrachloride which was identified to be mainly the corresponding starting benzyllamine hydrochloride.
In case of iso-propanol as a solvent, benzaldehyde, toluene, bibenzyl, ammonia and amixture of mono-, di- and tri-benzylamines were the only products obtained.
It can be concluded that photolysis of each amine starts with the homolytic fission of (C-N) bond into the correspondding amino radicals and benzyl radicals which consequently contribute for the formation of the identified products.
A mechanism was postulated for the formation of alkyllisocyanide separated when using carbontetrachloride and chloroform as solvents which was further emphasized by the results obtained on photolysis of the aryl-amines namely aniline, and E-toluidines in carbontetracloride. chloroform or methylene chloridqas.
