Abstract
The invention relates to α-sulfonylamino-acetonitrile derivatives of the general formula (I) including the optical isomers thereof and mixtures of such isomers, wherein Ar, and Arindependently of each other stand for an optionally substituted aryl or heteroaryl group, R, and Rstand independently of each other for hydrogen, optionally substituted C,-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; Rdesignates hydrogen, C-Calkenyl, C-Calkynyl or optionally substituted C,-Calkyl; Ris optionally substituted C,-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; Rand Rare independently of each other hydrogen or optionally substituted C-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; R, and Rare independently of each other hydrogen or optionally substituted C,-Calkyl, optionally substituted C-Calkenyl, C-Calkynyl or optionally substituted C-Ccycloalkyl; W designates a bridge selected from —O— —S(O)m— or —NR—; X designates a direct bond or a bridge selected from —O—, —S(O)m— or —NR—; a and b independently of each other stand for a number 1, 2 or 3; and c and m independently of each other stand for a number zero, 1 or 2. These compounds possess useful plant protecting properties and may advantageously be employed in agricultural practice for controlling or preventing the infestation of plants by phytopathogenic microorganisms, especially fungi.
