and to salts thereof.
Moreover, the invention relates to processes and intermediates for the preparation of these compounds and to their use for controlling animal pests and harmful fungi.
Phenylacetic acid derivatives for pest control have been disclosed in the literature (cf. WO-A 95/18789, WO-A 95/21153, WO-A 95/21154), but they are not yet satisfactory with a view to their activity.
It is an object of the present invention to provide novel compounds of this type which have an improved activity.
We have found that this object is achieved by the phenylacetic acid derivatives I defined at the outset. Moreover, we have found processes and intermediates for their preparation, compositions comprising them for controlling animal pests and harmful fungi, and their use for these purposes.
The compounds I are accessible via various routes by processes known per se.
When synthesizing the compounds I, it is, in principle, irrelevant whether the group —C(X)—CO—Y—R
1
or the group
is first synthesized.
The synthesis of the group —C(X)—CO—Y—R
1
is disclosed, for example, in the publications cited at the outset and in the following: EP-A 242 070, EP-A 254 426, EP-A 370 629, EP-A 398 692, EP-A 422 597, EP-A 463 488, EP-A 472 300, EP-A 513 580, EP-A 656 352, German Application P 44 20 416.7.
When synthesizing the group
a procedure is generally followed in which a benzyl derivative of the formula II is reacted with a hydroxyimine of the formula III.
L
1
in formula II is a nucleophilically exchangeable leaving group, eg. halogen or sulfonate groups, preferably chlorine, bromine, iodine, mesylate, tosylate or triflate.
The reaction is carried out in a manner known per se in an inert organic solvent in the presence of a base, eg. sodium hydride, potassium hydroxide, potassium carbonate or triethylamine, following the methods described in Houben-Weyl, 4th Edition, Vol. E 14b, p. 370 et seq. and ibd. Vol. 10/1, p. 1189 et seq.
The hydroxyimine III which is required is obtained, for example, by reacting a corresponding dihydroxyimine IV with the compound of the formula VI
L
2
in formula VI is a nucleophilically exchangeable leaving group, eg. halogen or sulfonate groups, preferably chlorine, bromine, iodine, mesylate, tosylate or triflate.
The reaction is carried out in a manner known per se in an inert organic solvent in the presence of a base, eg. potassium carbonate, potassium hydroxide, sodium hydride, pyridine or triethylamine as described in: Houben-Weyl, 4th Edition, Vol. E 14b, p. 307 et seq., p. 370 et seq. and p. 385 et seq.; ibid., 4th Edition, Vol. 10/4, p. 55 et seq., p. 180 et seq. and p. 217 et seq.; ibid., 4th Edition, Vol. E 5, p. 780 et seq.
Those compounds of the formula IV which are not already known can be prepared by methods known per se (cf. Gazz. Chim. Ital. 59 (1929), 719; Collect. Bull. Soc. Chim. Fr. 17 (1897), 71).
Alternatively, the compounds I can also be obtained by reacting the benzyl derivative II first with the dihydroxyimino derivative IV to give a corresponding benzyl oxime of the formula V, V subsequently being reacted with a compound of a [sic] formula VI to give I.
The reaction is carried out in a manner known per se in an inert organic solvent in the presence of a base, eg. potassium carbonate, potassium hydroxide, sodium hydride, pyridine or triethylamine following the methods described in Houben-weyl, 4th Edition, Vol. 10/1, p. 1189 et seq., Vol. E 14b, p. 307 et seq., p. 370 et seq. and p. 385 et seq., Vol. 10/4, p. 55 et seq., p. 180 et seq. and p. 217 et seq., Vol. E 5, p. 780 et seq.
Similarly, it is also possible to prepare the hydroxyimine [sic] of the formula III which is required from a carbonylhydroxyimine VII by reacting the latter with a hydroxylamine IXa or a salt thereof IXb.
Q

in formula IXb is the anion of an acid, in particular of an inorganic acid, eg. halide, such as chloride.
The reaction is carried out in a manner known per se in an inert organic solvent following the methods described in EP-A 513 580; Houben-Weyl, 4th Edition, Vol. 10/4, p. 73 et seq., Vol. E 14b, p. 369 et seq. and p. 385 et seq.
Those compounds of the formula VII which are not already known can be prepared by methods known per se (J. Am. Pharm. Assoc. 35 (1946), 15).
Alternatively, the compounds I can also be obtained by reacting the benzyl derivative II first with the carbonylhydroxyimino derivative VII to give a corresponding benzyloxyimine of the formula VIII, VIII subsequently being reacted with the hydroxylamine IXa or the salt thereof IXb to give I.
The reaction is carried out in a manner known per se in an inert organic solvent following the methods described in Houben-Weyl, 4th Edition, Vol. E 14b, p. 369 et seq., Vol. 10/1, p. 1189 et seq. and Vol. 10/4, p. 73 et s
