Title:
CYCLOBUTANE DICARBOXYLIC ACID ISOIMIDES, THEIR MANUFACTURE AND FUNGICIDE CONTAINING THEM
Document Type and Number:
Japanese Patent JPS56161382
Kind Code:
A
Abstract:
The invention relates to cyclobutanedicarboxisoimides of the formula I (I) wherein one of X and Y is oxygen and the other is each of R1 and R6 independently is methyl or ethyl, each of R2 and R3 independently is hydrogen, fluorine or methyl, or R2 is aceto hydrogen or methyl, while R3 and R4 together can also form an additional valency in the 4-membered cycloaliphatic ring. These compounds are suitable for controlling a variety of phytopathogenic fungi. They can be obtained by cyclizing the corresponding cyclobutanedicarboxylic acid monoamides in the temperature range from about -20 DEG to +100 DEG C., in the presence of dehydrating agents such as acetic anhydride or N,N'-dicyclohexylcarbodiimide.
