Abstract: Novel ortho-(mono-substituted amino)phenylimines being intermediates to psychotropic drugs and other drugs are economically and industrially prepared by reacting anilines with nitriles in the presence of a boron trifluoride ether adduct and a halide-type Lewis acid, if necessary together with an organic base. Furthermore, the imines can be hydrolyzed with an acid to afford the corresponding ketones.

Abstract: Novel herbicidal 1-cyclyl or polycyclyl substituted 1H-imidazole-5-carboxylic acid derivatives, compositions containing these compounds as active ingredients, and a method for controlling weeds, preferably selectively in crops of useful plants. Processes for making these novel compounds.

Abstract: Certain .alpha.-[(2-nitro-1H-imidazol-1-yl)methyl]-aziridinylethanols and the corresponding aziridine-ring opened analogs are useful as radiation sensitizers for X-irradiation therapy of tumors.

Abstract: A method of extracting benzo-c-phenanthridine alkaloids from plants of the families Papaveraceae, Fumariaceae, and Berberidaceae, comprising grinding the plant, extracting the ground plant with acidulated methanol or acidulated ethanol, precipitating the extract with an acid salt soluble in the solvent used, redissolving the precipitated salt in water, adding sufficient acid to form a precipitate, and collecting the precipitate so formed.
