2-DIETHYLAMINOVINYL DERIVATIVES OF HALOGENATED 1,4-QUINONES: SYNTHETIC AND STRUCTURAL ASPECTS

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 lie practically in one plane.
