The effects of some metal ions on the amination and arylation of 5,8-quinolinedione (<B>1</B>) and on the amine displacement of 6-piperidino-5,8-quinolinedione have been investigated. The reaction of <B>1</B> with various amines in chloroform or ethanol was specifically promoted by Ni(II) ions to give selectively the corresponding 6(substituted amino)-5,8-quinolinediones. With <I>N</I>,<I>N</I>-dialkylanilines in acetic acid the reaction was strongly promoted by Cu(II) ions to give exclusively 6-arylated products, 6-[<I>p</I>-(dialkylamino)phenyl]-5,8-quinolinediones. The metal chelate complex was proposed as an activated intermediate.
