The reaction of halogenated quinones with a variety of secondary amines in the presence of acetaldehyde proceeds via intermediate formation of enamines and produces mono quinonic enaminones. The use of two equivalents of enamine results in both symmetrical and nonsymmetrical bis-derivatives.

Diethylaminovinyl derivatives of halogenated 1,4-quinones (enaminoquinones) are produced by the interaction of halogenated 1,4-quinones with N,N-diethyl-N-vinylamine obtained in situ from Et2NH and MeCHO. Molecular and crystal structures of enaminoquinones halogenated in the quinone fragment are determined. It is shown that in the solid phase, atoms of the entire push-pull system of enaminoquinones
