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 Ar1, and Ar2independently of each other stand for an optionally substituted aryl or heteroaryl group, R1, and R2stand independently of each other for hydrogen, optionally substituted C1,-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; R3designates hydrogen, C3-C5alkenyl, C3-C5alkynyl or optionally substituted C1,-C5alkyl; R4is optionally substituted C1,-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; R5and R6are independently of each other hydrogen or optionally substituted C1-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; R7, and R8are independently of each other hydrogen or optionally substituted C1,-C5alkyl, optionally substituted C2-C5alkenyl, C2-C5alkynyl or optionally substituted C3-C6cycloalkyl; W designates a bridge selected from —O— —S(O)m— or —NR3—; X designates a direct bond or a bridge selected from —O—, —S(O)m— or —NR3—; 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.
