Phenyl Ketone

Methyl cyanoacctate, cyanoacetamide, and malonitrile readily add to vinyl phenyl ketone to give trimolecular products, while nitromethane gives a substance composed of one molecule of nitro compound and three molecules of unsaturated ketone. The reactions of the delta ketonic nitrile formed from the ester are described in detail; it is transformed into reduced pyridine derivatives, and a secondary open chain nitrile. The latter, in turn, is converted into pyridine and hydropyridine derivatives.
