Abstract: Process for the preparation of N-substituted 3,4,5,6- tetrahydrophthalimides of the formula I in which R represents hydrogen or fluorine R is hydrogen, chlorine, bromine or a C1- to C4-alkyl group and in which R represents a C1- to C6-alkyl or a C5- to C6-cycloalkyl group, by reacting an aldehyde of the formula II with a phosphorane of the formula III in which Ar represents an unsubstituted or substituted phenyl radical, at temperatures from -10 DEG C to 100 DEG C and in the presence of a solvent.

Abstract: Naphthalene-1-carboxylic acid (1-naphthoic acid) of the general formula I in which R represents fluorine, chlorine or bromine, R and R independently represent hydrogen, bromine or chlorine, and its functional compounds, i.e. in particular salts, esters, acid amides and N,N-dialkylhydroxylamine-O-acyl compounds, with the proviso that, in the event that R = R = hydrogen, the free acid, its methyl ester and its di-sec-butylamide are not protected by patent rights, their preparation and their use as plant treatment agents which have, in particular, a herbicidal activity.
