Cyanosulfonylethyltriazoles and their use as fungicides

The present invention is concerned with substituted 1-((2-cyano-2-(substituted sulfonyl)ethyl)-1,2,4-triazoles of formula (I) wherein R and R' are each independently alkyl or alkyl substituted with halo, alkoxy or haloalkoxy; aryl or aralkyl, both of which may be substituted on the aryl portion of the moiety with one or more substituents each independently selected from halo, alkyl, haloalkyl, alkoxy, haloalkoxy, dialkylamino, phenyl, phenoxy, or phenyl or phenoxy substituted with one or two substituents each independently selected from halo and alkyl; heterocyclyl or heterocyclylalkyl, both of which may be substituted on the heterocyclyl ring with one or two substituents each independently selected from halo and alkyl; and their salts, enantiomorphs and metal salt complexes.The present invention is also concerned with the use of such triazoles as fungicides.
