Abstract
A class of novel heterocyclicacetonitriles which is useful in the control of fungi, especially bitunicate asci and unitunicate asd, has been discovered. These compounds are of the general formula: ##STR1## wherein Ar.sub.1 and Ar.sub.2 are substituted or unsubstituted aryl groups; Het is a six-membered nitrogen-containing heterocyclic ring; n is the integer 2 or 3; and the agronomically acceptable enantiomorphs, add addition salts and metal complexes thereof.

A compound of the formula:
- ##STR7## wherein Ar.sub.1 is selected from an optionally substituted C.sub.6 to C.sub.10 aryl group with up to three substituents independently selected from the group consisting of halogen, nitro, cyano, (C.sub.1 -C.sub.12) alkyl, (C.sub.1 -C.sub.12) haloalkyl, (C.sub.3 -C.sub.8) cycloalkyl, (C.sub.5 -C.sub.8) cycloalkenyl, (C.sub.2 -C.sub.12) alkenyl, (C.sub.2 -C.sub.12) alkynyl, (C.sub.1 -C.sub.12) alkoxy, (C.sub.1 -C.sub.12) haloalkoxy, (C.sub.1 -C.sub.12) alkylthio, (C.sub.1 -C.sub.12) alkylsulfinyl, (C.sub.1 -C.sub.12) alkylsulfonyl, phenyl, phenoxy, phen(C.sub.1 -C.sub.12)alkyl, phen(C.sub.2 -C.sub.12)alkenyl, phen(C.sub.2 -C.sub.12)alkynyl and (C.sub.5 -C.sub.6)cycloalkyl (C.sub.1 -C.sub.6)alkyl;
- Ar.sub.2 is an optionally substituted (C.sub.6 -C.sub.10) aryl group wherein the substituents are independently selected from the substituents enumerated above for Ar.sub.1 ;
- or Ar.sub.2 may be thiopheneyl or furanyl;
- Het is a pyridyl ring;
- n is the integer 2 or 3;
- and the agronomically acceptable enantiomorphs, acid addition salts and metal complexes thereof.
A method of controlling fungi comprising contacting said fungi or the locus of said fungi with a fungicidally effective amount of a compound of the formula:
- ##STR8## wherein Ar.sub.1 is selected from an optionally substituted C.sub.6 to C.sub.10 aryl group with up to three substituents independently selected from the group consisting of halogen, nitro, cyano, (C.sub.1 -C.sub.12) alkyl, (C.sub.1 -C.sub.12) haloalkyl, (C.sub.3 -C.sub.8) cycloalkyl, (C.sub.5 -C.sub.8) cycloakkenyl, (C.sub.2 -C.sub.12) alkenyl, (C.sub.2 -C.sub.12) alkynyl, (C.sub.1 -C.sub.12) alkoxy, (C.sub.1 -C.sub.12) haloalkoxy, (C.sub.1 -C.sub.12) alkylthio, (C.sub.1 C.sub.12) alkylsulfinyl, (C.sub.1 -C.sub.12) alkylsulfonyl, phenoxy, phenyl, phen(C.sub.1 -C.sub.12)alkyl, phen(C.sub.2 -C.sub.12) alkenyl, phen(C.sub.2 -C.sub.12)alkynyl and (C.sub.5 -C.sub.6)cycloalkyl (C.sub.1 -C.sub.6 alkyl;
- Ar.sub.2 is an optionally substituted (C.sub.6 -C.sub.10) aryl group wherein the substituents are independently selected from the substituents enumerated above for Ar.sub.1 ;
- or Ar.sub.2 may be thiopheneyl or furanyl;
- Het is a pyridyl ring;
- n is the integer 2 or 3;
- and the agronomically acceptable enantiomorphs, acid addition salts and metal complexes thereof.
