HETEROCYCLICACETONITRILES AND FUNGICIDAL USE

摘要

A class of novel heterocyclicacetonitriles which is useful in the control of fungi, especially bitunicate asci and unitunicate asci, has been discovered. These compounds are of the general formula: (I) wherein Ar1 and Ar2 are substituted or unsubstituted aryl groups; Het is a sixmembered nitrogen-containing heterocyclic ring; n is the integer 2 or 3; and the agronomically acceptable enantiomorphs, acid addition salts and metal complexes thereof. 52
