Abstract: 2118308 9323377 PCTABS00028 A process is disclosed for preparing N-allyl compounds having general formula (I), in which (II) stands for a N-containing aromatic heterocycle; R1, R3 and R4 represent independently from each other hydrogen or C1-C4-alkyl; R2 stands for hydrogen or methyl; n equals 1, 2, 3 or 4 and X- is an anion for rendering water-soluble. The process is characterized in that compounds having formula (II) are reacted in an aqueous medium with compounds having formula (III), in which A stands for a residue which can be split as an anion. These compounds are very suitable as brighteners for nickel-plating.
