Abstract
Described are a compound of formula (I), wherein X and Y are, independently of one another, florine or chlorine, and Z is O or S; and where appropriate their possible tautomers, in each case either in free form or in the form of a salt; a method for the preparation and application of these compounds and their tautomers, pesticides whose active ingredient is selected from these comounds and their tautomers; and a method for the preparation and application of these compositions, intermediates, in free form or in the form of a salt, for the preparation of these compounds and where appropriate their tautomers in free form or in the form of a salt. 1
Claims15
A compound of formula 15
- wherein X and Y are, independently of one another, fluorine or chlorine, and Z is O or S;
- and where appropriate their possible tautomers, in each case either in free form or in the form of a salt.
A method for preparing the compounds of formula (I) and where appropriate their tautomers, in each case in free form or in the form of a salt, comprising
- a) the reaction of a compound of formula 16
- wherein X and Y are as defined for formula (I) and Q is bromine or iodine, with a compound of formula 17
- and
- b) where appropriate, for preparing a compound of formula (I), wherein Z is S, the reaction of the resulting compound of formula (I), wherein Z is 0, with [2,4-bis(methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide] or with phosphorus pentasulfide;
- and in each case, if so desired, the conversion of a compound of formula (I) obtainable according to the method or by other means, or a tautomer thereof, present in free form or in the form of a salt, into a different compound of formula (I) or a tautomer thereof, the separation of a mixture of isomers obtainable according to the method and isolation of the desired isomers and/or the conversion of a free compound of formula (I) obtainable according to the method, or a tautomer thereof, into a salt, or a salt obtainable according to the method from a compound of formula (I), or a tautomer thereof, into the free compound of formula (I), or a tautomer thereof, or into a different salt.
