    Abstract: The invention comprises ethyleneimine derivatives of the formula : in which R is an alkyl, cycloalkyl or aryl group. They may be obtained by reacting an appropriate thiophosphoric monoester dihalide, e.g. chloride or bromide with ethyleneimine in the presence of an acid-binding agent. Specified acid binding agents are tertiary amines, e.g. trimethylamine or triethylamine, anhydrous ammonia, sodium carbonate, potassium carbonate, sodium acetate, and sodium hydroxide. The reaction may be carried out in an aqueous medium or in an organic solvent, e.g. a hydrocarbon, chlorinated hydrocarbon, ketone or ether. Examples are given for the production of products of the above formula in which R is ethyl, butyl, cyclohexyl, isobutyl, n-amyl, and phenyl respectively. The products have the property of checking the growth of malignant tumours.
