Abstract

Compounds of the formula I in which R1, R2, R3, R4 and X have the meaning defined in Patent Claim 1, are potent insecticides. They form the active substances of the novel insecticide preparations. They are prepared by reacting a compound of the formula II with a compound of the formula III R1-N=C=X or with a compound of the formula and, if appropriate, further reacting the resulting compound, in which R4 equals H, with an R4-halide.

Description

(54)1,3,4 SUBSTITUTED PYRAZOLINE DERIVATIVES
(71) We, N.V. PHILIPS’ GLOEILAMPENFABRIEKEN, a limited liability Company, organised and established under the laws of the Kingdom of the
Netherlands, of Emmasingel 29, Eindhoven, the Netherlands, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to 1,3,4 substituted pyrazoline derivatives and to insecticidal compositions which contain the derivative as an active ingredient.
It is known from German Offenlegungsschrift 2,304,584 in the name of the Applicant that pyrazoline compounds which in the 1,3 or 1,3,5 positions of the pyrazoline ring are provided with a substituent, exert a biocidal activity with respect to arthropods, for example mites and insects.
It has now been found that new pyrazoline compounds as defined by the formula below and which contain substituents in the 1, 3 and 4 positions of the pyrazoline ring, have a very strong insecticidal activity.
The compounds according to the present invention may be represented by the general formula
in which Rl is an alkyl group, a cycloalkyl group, a phenylalkyl group of which the phenyl nucleus may be substituted with halogen, alkyl or nitro, a heterocyclic ring which contains 1 or 2 nitrogen atoms and may be substituted with halogen, alkyl or nitro, a phenyl group or a phenyl group which is substituted in the 2, 3 or 4 positions with 1 or 2 substituents selected from halogen, alkyl, haloalkyl, cycloalkyl, alkylthio, alkoxy, dialkylamino, alkylsulphonyl, acyl, acylamino, cyano, nitro, phenyl, halophenyl, phenylthio, phenoxy and phenylalkyl radical, R, is an alkyl group, a cycloalkyl group, a pyridyl group or a thienyl group which may be substituted with halogen, alkyl or nitro, a phenyl group or a phenyl group substituted with 1 or 2 substituents selected from halogen, alkyl, haloalkyl, cycloalkyl, alkylthio, alkoxy, mono- or dialkylamino, nitro, phenyl, halophenyl and cyano; Rl is a hydrogen atom, an alkyl group having 1-15 carbon atoms, a phenylalkyl group, a cycloalkyl group or a halomethylthio group; R, is an alkyl group having 5-10 carbon atoms or an alkyl group having 1 to 6 carbon atoms which is substituted by cycloalkyl, alkoxy, alkylthio, nitro, halogen, cyano, alkoxycarbonyl, phenyl optionally substituted by nitro, halogen or alkyl, phenoxy, phenylthio, phenylsulphinyl, phenylsulphonyl, dialkylamino the alkyl groups of which may form together with the nitrogen atom to which they are bound a saturated or an unsaturated, optionally substituted heterocyclic ring which may contain a second hetero atom, alkylphenyl, diphenylamino, N,N-dialkylcarbamoyl or N,N-dialkylsulphamoyl; with the proviso that (a) when an alkyl group, phenylalkyl group, alkylthio group, alkoxy group, alkylamino group, dialkylamino group, or an alkylsulphonyl group occurs in the substituents R, to R4 then the alkyl group contains from 1 to 4 carbon atoms, (b) when the cycloalkyl group occurs in the substituents Rz to R, then the cycloalkyl group contains from 3 to 6 carbon atoms and (c) that when Rl is a phenyl group substituted by phenylthio, phenoxy or phenylalkyl and/or R4 is a phenylalkyl, cycloalkyl or halomethylthio group, R3 may also have a meaning mentioned for
R2; and X is an oxygen atom or a sulphur atom.
In one embodiment of the invention there is provided a compound of the formula given above, in which formula, Rn represents an alkyl group having from 1 to 6 carbon atoms which is substituted with an alkoxy group having from l to 4 carbon atoms, or
R3 is an alkyl group having from 1 to 6 carbon atoms substituted with a dialkylamino group in which the alkyl radicals may form a heterocyclic ring with the nitrogen atom and Rl, R2, R4 and X are as hereinbefore defined.
Structurally related 1,3,4 substituted pyrazoline derivatives are the subject matter of the United Kingdom Patent No. 1 514285. The compounds described in said Patent No. 1 514 285 also have good insecticidal properties.
Thus if an alkyl group, phenylalkyl group, alkylthio group, alkoxy group, alkyl- amino group, dialkylamino group or an alkylsulphonyl group occurs in the substituents Rl to R4, then the alkyl radical present in such group contains from 1–4 carbon atoms; and when the cycloalkyl group occurs the cycloalkyl group contains from 3-6 carbon atoms.
If an acyl group or an acylamino group occurs in R1, then the acyl part of such a group is preferably derived from an aliphatic monocarboxylic acid, for example acetic acid or propionic acid.
When R1 represents a heterocyclic ring which contains 1 or 2 nitrogen atoms, this is preferably either a pyridine or pyrimidine ring.
It has been found by biological evaluation examination that the compounds of the invention have a good insecticidal activity and, in particular at low dosages, they are capable of controlling, for example, beetles, larvae of beetles, larvae of mosquitoes and caterpillars.
It has surprisingly been found that the insecticidal activity of the compounds of the invention is considerably better than that of the known 1,3- and 1,3,5-substituted pyrazolines. It has been found that in many cases the compounds of the invention also have a good activity against the yellow fever mosquito in addition to an excellent activity against both the Colorado beetle and the caterpillar. Compounds from the known series of 1,3,5-substituted pyrazolines, and 1,3-substituted compounds have a good activity against larvae of the Colorado beetle, a less strong activity against the caterpillar (larvae of the Cabbage White butterfly) and, in general no or substantially no activity against larvae of the yellow-fever mosquito.
The active compounds of the invention show, for example an optimal activity, in a concentration of 0.3-3 ppm against the larvae of the Colorado beetle, and in a concentration of 1.3-30 ppm show a maximum activity against the caterpillar and furthermore, in a concentration of 0.03-0.3 ppm show a maximum activity against larvae of the yellow-fever mosquito. The following active compounds are particularly suitable,
