| abstract |
The present invention relates to novel compounds of the formula (I) <IMAGE> (I) wherein R1 and R2 are the same or different and stand for alkyl having 1 to 4 carbon atoms optionally substituted by one or more halogen atoms, alkenyl having 2 to 6 carbon atoms, cycloalkyl having 3 to 6 carbon atoms, phenyl or lower alkoxy-alkyl group, R3 stands for alkyl having 1 to 6 carbon atoms or alkenyl having 2 to 6 carbon atoms, R4 and R5 are the same or different and represent hydrogen, alkyl having 1 to 6 carbon atoms, alkenyl having 2 to 6 carbon atoms, cycloalkyl having 3 to 6 carbon atoms, phenyl, benzyl, phenyl substituted by one or more alkyl having 1 to 3 carbon atoms and/or by one or more halogen atoms, lower alkoxy-alkyl, a group of the formula -(CH2)n-R6, wherein n is an integer between 0 to 3 and R6 stands for a 3 to 7 membered saturated or unsaturated ring comprising 1 to 3 heteroatoms, said heteroatoms can be selected from the group of nitrogen and/or oxygen and/or sulphur, and R4 and R5 can together form with the adjacent nitrogen atom a hexamethylene-imino group. The compounds of the invention exhibit acaricidal, insecticidal and fungicidal activity. |
