    摘要: A process for the preparation of N-allyl compounds of the general formula I ##STR1## in which ##STR2## denotes a nitrogen-containing heterocyclic compound, R.sup.1, R.sup.3, and R.sup.4 independently denote hydrogen or C.sub.1 -C.sub.4 alkyl,R.sup.2 denotes hydrogen or methyl,n is equal to 1, 2, 3, or 4, andX denotes a water-solubilizing anion,wherein a compound of formula II ##STR3## is caused to react, in aqueous medium, with a compound of formula III ##STR4## in which A denotes a radical which can be eliminated as an anion. The compounds produced by the process of the invention are very well suited for use as brighteners in nickel electroplating.
