Readily available N-monosubstituted trifluoroacetamides are transformed into isothiocyanates in good yield by reaction, at room temperature, with carbon disulfide in acetonitrile in the presence of anhydrous sodium hydroxide/potassium carbonate basic mixture.
The present invention provides benz[f]isoindolines, useful in the treatment of aggression, a process for their preparation and compositions containing these compounds.
The present invention concerns novel hydro-4-phenyl-benz[f]isoindoline derivatives, of the formula ##STR1## wherein R is hydrogen or substituted or unsubstituted alkyl, R.sub.1 and R.sub.2 are hydrogen, halogen or alkyl, and either X and Y are hydrogen, or X and Y together are an additional bond, Useful as analgesics and antidepressants.
