ChemInform Abstract
Quaternization of the nitrogen atom of both dimethylamino groups in α-substituted dimethylamino hydrazones (I) followed by Hoffman decomposition of the resulting diiodides (II) provides a novel and convenient route for the synthesis of α-substituted acrylonitrile derivatives (III) (5 examples).
