The possibility of aminating alkyl halides with urea was the prime interest of the research undertaken in this thesis. Alkyl halides and urea react only to a slight degree. However the reaction is rapid when dimethylformamide is used as a solvent.

In working with compounds containing halogen on the aromatic ring we always found the halogen to be replaced by the amino group. With alkyl halides, however, this was not so. In the case of the reaction between an alkyl halide and urea in a solvent, a compound of composition close to that of a di-alkylurea was isolated and the halide ion produced. The reaction yield was calculated from the results obtained by the analysis for the halide ion.

There were a number of conditions which had an effect on increasing the final yield of the alkylurea: a. by varying temperature; b. changing: the solvent; c. length of time that the reaction was run; d. an increase of the urea concentration in the experiment; and e. also, by an increase in the alkyl halide concentration.

The rate of reaction between the halogens varied as normally expected: iodide > bromide > chloride.
