ABSTRACT:
Substituted N-cyanomethyl-2-pyridinones were prepared by the reaction of alkali metal substituted-2-pyridinates with monohaloacetonitriles and found to possess insecticidal properties. The alkali metal substituted-2-pyridinates can be preformed or prepared from the corresponding 2-halopyridines or 2-pyridinols in the reaction medium. N-cyanomethyl-3-fluoro-5-(trifluoromethyl)-2-pyridinone, for example, was prepared from 2,3-difluoro-5-(trifluoromethyl)pyridine and found to control aster leafhoppers both on contact and systemically.
