Abstract: A 3,4,5,6-tetrahydrophthalamide derivative and a 3,4,5,6-tetrahydroisophthalimide derivative, both having an excellent efficay as the active ingredient of a herbicide, and an industrial process for efficiently producing these higher-performance, herbicidally active compounds. A tetrahydrophthalamide derivative represented by general formula (I) is produced by the reaction of a tetrahydrophthalimide derivative, prepared by the reaction of a halogenated 5-cycloalkyloxyaniline derivative with 3,4,5,6-tetrahydrophthalic anhydride, or of the tetrahydroisophthalimide derivative of the invention with various amines. These tetrahydrophthalamide and tetrahydroisophthalimide derivatives have an excellent herbicidal effect in the treatment of lowland and upland soils and foliage treatment. The tetrahydroisophthalimide derivative is useful also as an intermediate for producing the tetrahydrophthalamide derivative and the like.

Description: Technical Field In recent years, chemical agricultural agents have been essential materials for modern agriculture, and, as social demands for these chemical agricultural agents including herbicides, agents having low toxicity and residue and high selectivity to crops are desired. The present invention is to provide novel herbicides which meet the above-described social demands. More specifically, the present invention relates to a 3,4,5,6-tetrahydrophthalamide derivative represented by the general formula (I): wherein X 1 represents a halogen atom, X 2 represents a hydrogen atom or a halogen atom, R 1 represents a cycloalkyl group having from 3 to 8 carbon atoms which may be substituted, R 2 represents a hydrogen atom, a chlorine atom or a methyl group, R 3 and R 4 each independently represents a hydrogen atom, an alkyl group having from 1 to 12 carbon atoms, a cycloalkyl group having from 3 to 9 carbon atoms, an aryl group having from 6 to 10 carbon atoms, an alkenyl group having from 3 to 5 carbon atoms or an alkynyl group having from 3 to 5 carbon atoms, or R 3 and R 4 may form, together with the nitrogen atom to which they are attached, a substituted or unsubstituted alicyclic heterocyclic ring; a process for preparing the same; and a herbicide containing the same as an active ingredient. Further, the present invention relates to a 3,4,5,6-tetrahydroisophthalimide derivative represented by the general formula (V): wherein X 1 represents a halogen atom, X 2 represents a hydrogen atom or a halogen atom, R 1 represents a cycloakyl group having from 3 to 8 carbon atoms which may be substituted, A-B represents NH-C(OH) or N=C, and R 2 represents a hydrogen atom, a chlorine atom or a methyl group; a process for preparing the same; and a herbicide containing the same as an active ingredient. Also, the 3,4,5,6-tetrahydroisophthalimide derivatives represented by the general formula (V) per se are useful as active ingredients of the herbicide, and also, for example, 3,4,5,6-tetrahydrophthalimideohydroxy derivatives represented by the general formula (V) wherein A-B represents NH-C(OH) can be easily converted by dehydration reaction under heating into the 3,4,5,6-tetrahydrophthalimide derivatives represented by the general formula (II) which are useful as active ingredients for the herbicides disclosed in Japanese Patent Publication (Kokai) No. 4-164067. (Refer to Reference Example 19 below.) Furthermore, the 3,4,5,6-tetrahydroisophthalimide derivatives represented by the general formula (IV) can be easily converted by reacting with various amines into the 3,4,5,6-tetrahydrophthalamide derivatives represented by the general formula (I) which are the compounds of the present invention and are useful as active ingredients as herbicides. Technical Background Hithertofore, as 3,4,5,6-tetrahydrophthalimide derivatives having an herbicidal activity, for example, Japanese Patent Publication (Kokai) Nos. 54-154737, 55-157546 (Japanese Patent Publication No. 63-13981), 59-51250, 60-252457, 61-43160, or U.S. Patent 4,613,675 have been known, but the compounds having a cycloalkyloxy group at the 5-position of the phenyl ring on the nitrogen atom thereof have not been known. Also, it is conventionally known that the 3,4,5,6-tetrahydrophthalamic derivatives having a carboxylic acid residual group and an amido group which are synthesized by reacting an aniline derivative with 3,4,5,6-tetrahydrophthalic anhydride (for example, the compounds disclosed in Japanese Patent Publication (Kokai) Nos. 48-44425, 54-125640 and 59-67255) exhibit a herbicidal activity, but the 3,4,5,6-tetrahydroisophthalimide hydroxy derivatives represented by the structure of the general formula (V') having a cycloalkyloxy group at the 5-position of the phenyl ring on the nitrogen atom thereof have not been known. Further, as 3,4,5,6-tetrahydroisophthalimide derivatives, for example, the compounds disclosed in Japanese Patent Publication (Kokai) No. 53-23962, Japanese Patent Publication No. 3-69907, Japanese Patent Publication No. 4-7347, and U.S. Patent No. 3,990,880 have been known, but the compounds having a cycloalkyloxy group at the 5-position of the phenyl ring on the nitrogen atom thereof have not been known. Development of excellent herbicides is required for protecting important crops, for example, rice, soybean, corn, wheat or cotton or beat from weeds, and, further, increasing the productivity of these crops, and contributes to the labor-saving of the agricultural works and hence to the stabilization of the food economy. For such herbicides, development of agents having the following conditions is required. That is, from the viewpoint of effects, agents having a broad herbicidal spectrum and at the same time a high safety to crops, and also having a high activity to perennial weeds which are difficult to remove are desirable, and, from the viewpoint of labor-saving of works, agents which are effective with a less number of treating times with the agent, and the effect thereof lasts for an appropriate period of time are desirable. The conventionally known 3,4,5,6tetrahydrophthalamide derivatives or 3,4,5,6-tetrahydroisophthalimide derivatives per se exhibits good herbicidal effects, but it cannot be said that these derivatives necessarily satisfy the desirable requirements. Further, the above-described known compounds exhibit markedly different strength in the herbicidal activity or selectivity to crops by slight difference in the structure thereof (for example, the type and position of substituents), and, therefore, it is difficult to predict herbicidal activities and selectivities of new compounds merely from the similarity in the chemical structure. The present invention provides compounds which exhibit an excellent herbicidal activity in the treatment at a low amount and a high safety, and which are further useful as active ingredients of herbicides having an excellent selectivity to the crops. As a result of extensive studies from the above viewpoints, the present inventors found that the 3,4,5,6-tetrahydrophthalaimide derivatives in which a cycloalkyloxy group as a substituent has been introduced into the 5-position of the phenyl ring, rep-resented by the general formula (I): wherein X 1 , X 2 , R 1 , R 2 , R 3 and R 4 have the same meanings as above, and the 3,4,5,6-tetrahydroisophthalimide derivatives in which a cycloalkyloxy group as a substituent has been introduced at the 5-position of the phenyl ring, represented by the general formula (V): wherein X 1 , X 2 , R 1 and R 2 have the same meanings as above, have a high herbicidal activity against weeds by the treatment at a low dose and, also, a markedly reduced detrimental effect by the agent on main crops. The compounds of the present invention exhibit markedly excellent herbicidal activities in the treatment at a low dose in the stem-foliar treatment and the soil treatment in the field on various troublesome weeds, for example, broad leaf weeds such as Chenopodium album , Amaranthus viridis , Abutilon theophrasti , Stellaria media , Persicaria longiseta and Ambrosia elatior , and grass weeds such as Echinochloa crus-galli , Setaria viridis , Digitalia ciliaris , Eleusine indica and Alopecurus aequalis , but do not exhibit any troublesome detrimental effect by the agent on main crops, e.g., broad leaf crops such as soybean, cotton and beat, grass crops such as corn and wheat. Also, the compounds of the present invention exhibit markedly excellent herbicidal activities in the treatment at a low dose on various troublesome weeds in the paddy field, for example, grass weeds such as Echinochloa oryzicola and Echinochloa crus-galli , broad leaf weeds such as Lindernia pyxidaria , Rotala indica , Callitriche fallax and Monochoria vaginalis , Cyperus weeds such as Scirpus juncoides , Eleocharis acicularis , Cyperus difformis , Cyperus serotinus and Eleocharis kuroguwai , and Sagittaria pyamaea , whereas these compounds exhibit only very slight detrimental effects by the agent on the transplanted rice plants in the paddy field. Such a high selectivity of the compounds of the present invention can not be totally expected from conventional 3,4,5,6-tetrahydrophthalamide derivatives, and this characteristic is apparently brought about by introducing a cycloalkyloxy group into the 5-position of the phenyl ring thereof.

The reaction time varies depending upon the type of reaction materials, and generally the reaction is completed within 5 minutes to 24 hours. Also, the reaction can be carried out by adding a catalyst for the purpose of promoting the reaction. The catalyst which is generally used includes a basic compound such as triethylamine, N-methylmorpholine, pyridine, N,N-dimethylaniline, potassium carbonate and sodium carbonate. Further, the tetrahydroisophthalimide derivatives of the present invention represented by the above general formula (IV) which are starting mterials of the compounds (I) of the present invention can be prepared according to the process shown by the following formulae: wherein X 1 , X 2 and R 2 have the same meanings as defined above. More specifically, Step-1 is a step of reacting an aniline derivative presented by the general formula (VI) with a 3,4,5,6-tetrahydrophthalic anhydride represented by the general formula (VII) in an organic solvent at a low temperature to convert it into a 3,4,5,6-tetrahydroisophthalimidohydroxy derivative represented by the general formula (V').

The reaction temperature'is selected between 0°C and 100°C, but the reaction is preferably conducted at a low temperature below 50°C from the standpoint of good yields. After completion of the reaction, usual post-treatments are performed and, if necessary, the product can be purified by the procedure such as chromatography and recrystallization. Generally, in the reaction of the aniline derivative represented by the general formula (VI) with the 3,4,5,6-tetrahydrophthalic anhydride represented by the general formula (VII), the reaction chemically provides a ring-opened 3,4,5,6-tetrahydrophthalamic acid derivative represented by the following general formula (VIII): wherein X 1 , X 2 , R 1 and R 2 have the same meanings as defined above, due to attack of the amino group to the carbonyl group of the acid anhydride, but, in the case of using the aniline derivative (VI) having a cycloalkyloxy group at the 5-position of the phenyl ring, it is considered that an intramolecular cyclization further occurs easily due to steric and electronic factors whereby the product is obtained as a more stable 3,4,5,6-tetrahydroisophthalimidohydroxy derivative represented by the general formula (V'). Step-2 is a step of reacting a 3,4,5,6-tetrahydroisophthalimidohydroxy derivative represented by the general formula (V') in the presence of a dehydrating agent in an organic solvent to produce a 3,4,5,6-tetrahydroisophthalimide derivative represented by the general formula (IV).

Examples of the dehydrating agent include carbodiimides such as dicyclohexylcarbodiimide, diisopropylcarbodiimide and diethylcarbodiimide, halogenating agents such as thionyl chloride, 2,4,6-triisopropylbenzenesulfonyl chloride, mesitylenesulfonyl chloride, phosphorus oxychloride and phosgene, and polyphosphoric acid esters. Although the amount of the dehydrating agent to be used is not limited, the use of about 1 to 3 molar equivalents relative to the starting material is preferred from the standpoint of good yields and easy post-treatment.
