ABSTRACT:
An alpha-arylacrylonitrile is prepared by reacting an aryl ketone having a removable hydrogen alpha to the carbonyl group with an alkali metal cyanide and aluminum chloride, preferably in the presence of a solvent and a phase transfer catalyst. In a preferred embodiment, the aryl ketone is a tetralone, and the product is a 1-cyano-3,4-dihydronaphthalene which may then be dehydrogenated to a 1-cyanonaphthalene.
