Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
66 words
Urea and thiourea compounds of the general formula in which R' represents cycloalkyl with 5-8 carbon atoms in the ring, which may be optionally substituted by alkyl with 1-8 carbon atoms, R 2 represents alkyl with 1-8 carbon atoms, cycloalkyl with 5-8 carbon atoms in the ring or phenyl, X represents oxygen or sulphur, and Y represents halogen, alkyl with 1-8 carbon atoms, cyano or nitro.
Claim 2
Dependent Claim
66 words
Urea and thiourea compounds of the general formula in which R' represents cycloalkyl with 5-8 carbon atoms in the ring, which may be optionally substituted by alkyl with 1-8 carbon atoms, R 2 represents alkyl with 1-8 carbon atoms, cycloalkyl with 5-8 carbon atoms in the ring or phenyl, X represents oxygen or sulphur, and Y represents halogen, alkyl with 1-8 carbon atoms, cyano or nitro.
Claim 3
Dependent Claim
117 words
A process for the preparation of new urea or thiourea compounds of formula (1), characterised in that a) an N-benzyl-N-cycloalkylamine of the general formula in which R 1 and Y have the meanings stated in claim 1, is reacted with an isocyanate or isothiocyanate of the general formula in which R 2 and X have the meanings stated in claim 1, or (b) an N-benzyl-N-cycloalkyl carbamoyl (or thiocarbamoyl) halide of the general formula in which R 1 , X and Y have the meanings stated in claim 1, and Hal represents halogen, in particular chlorine or bromine, is reacted with an amine of the general formula in which R 2 has the meaning stated in claim 1.
Claim 4
Dependent Claim
16 words
A fungicidal composition, characterised in that it contains urea and thiourea compounds according to claim 1.
Claim 5
Dependent Claim
14 words
The use of urea and thiourea compounds according to claim 1 for combating fungi.
Claim 6
Dependent Claim
26 words
A process for the preparation of fungicidal compositions, characterized in that urea and thiourea compounds according to claim 1 are mixed with diluents and surface-active ingredients.
