Abstract
The reactions of 4-ethoxychromylium salts with some amines were studied. It was shown that o-hydroxyarylpyrazoles and chromone phenylhydrazones, respectively, are formed by the reaction of these salts with hydrazine and phenylhydrazine. The action of primary aromatic amines leads to replacement of the 4-ethoxy group by a 4-arylamino group, while the reaction of the 4-ethoxychromylium salts with N,N-diethylaniline gives 4-ethoxy-4′-diethylaminoflavylium salts.
