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.
