Process for the manufacture of benzimidazolones-(2) wherein an o-phenylenediamine is reacted with optionally alkylated urea in the ratio of 1 to 1.3 moles per mole o-phenylenediamine in an organic solvent which has a solubility in water of not more than 5 g/l and has a boiling point above 100° C, at a temperature between 100° and 200° C.

Aromatic amines (e.g., aniline) are selectively alkylated in an ortho nuclear position by reaction with an olefin (e.g., ethylene) in the presence of an aluminum anilide catalyst. Hydrogen halides (e.g., HCl) are added to increase the reaction rate.

New perfluoroalkyl derivatives of benzodiazepine are prepared by reacting an orthophenylenediamine with a beta-diketone at least one of whose alkyls is a C1 - C15 perfluoroalkyl. The stable products are useful as heat-exchange substances and as surfactants in organic solution.
