Aromatic amine derivatives

Abstract

Novel aromatic amine derivatives of specific structure are useful intermediates for herbicides. The aromatic amine compounds have the structure shown by formula [I]: ##STR1## wherein Ar and A are as defined herein.

Description

BACKGROUND OF THE INVENTION

This invention relates to novel aromatic amine derivatives.

Wheat, corn, rice, and soybean plants are important crops. A variety of herbicides have been applied in order to increase crop yields. Prior art herbicides are not satisfactory in herbicidal activity and safety to growing crops. There is a need for a safe herbicide which can control weeds at a low level of application while giving no or little phytotoxity to growing crops.

During our research to produce a herbicide which is applicable in a small amount to kill weeds without phytotoxity to growing crops, we have discovered novel aromatic amine derivatives which are useful as intermediates for herbicides meeting the above requirements.

SUMMARY OF THE INVENTION

An object of the present invention is to provide novel aromatic amine derivatives which are useful as intermediates for herbicides.

According to the present invention, there is provided a novel aromatic amine derivative of the general formula [I]: ##STR2## wherein Ar is a radical selected from the group consisting of ##STR3## wherein R.sup.1 to R.sup.15 and R.sup.17 to R.sup.38 may be the same or different and are independently selected from the group consisting of hydrogen, lower alkyl radicals, and lower alkoxyl radicals, R.sup.16 is selected from the group consisting of hydrogen, lower alkyl radicals, lower alkoxyl radicals and hydroxyl, with the proviso that R.sup.2 and R.sup.3, R.sup.6 and R.sup.7, R.sup.9 and R.sup.10, and R.sup.15, or R.sup.15 and R.sup.16 may, taken together, represent an alkylene chain, which may be substituted with a lower alkyl radical, to form a 5- or 6-membered ring with the carbon atoms to which they are attached, R.sup.11 and R.sup.12 may, taken together, represent an ethylene dioxyl radical, or R.sup.14 and R.sup.15 may, taken together, represent a dichloromethylene radical; and

A is a nitrogen atom or ##STR4## wherein X is selected from the group consisting of a hydrogen atom, a chlorine atom, a nitro radical, and a trifluoromethyl radical, when both R.sup.5 and R.sup.6 are methyl radicals and ##STR5## at least one of R.sup.7 and R.sup.8 does not represent hydrogen atom, when both R.sup.25 and R.sup.26 are methyl radicals and ##STR6## at least one of R.sup.23 and R.sup.24 does not represent hydrogen atom.

DETAILED DESCRIPTION OF THE INVENTION

The aromatic amine derivatives of the present invention have the general formula [I] as defined above.

Examples of the lower alkyl radicals represented by R.sup.1 through R.sup.38 include methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, etc. Examples of the lower alkoxyl radicals represented by R.sup.1 through R.sup.38 include methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, isobutoxy, sec-butoxy, etc.

The aromatic amine derivatives of the present invention may be prepared through a series of reactions as shown by the following formulae (1) and (2). ##STR184## The reaction of formula (1) may be carried out by agitating the reagents in an aromatic hydrocarbon such as benzene, toluene, and xylene, an aprotic polar solvent such as N,N-dimethylformamide and 1-methyl-2-pyrrolidone, or a mixture thereof in the presence of a base such as NaOH, KOH, Na.sub.2 CO.sub.3, K.sub.2 CO.sub.3, NaH at a temperature of from 20.degree. C. to 150.degree. C. The reaction of formula (2) may proceed in a solvent inert to the reaction, for example, benzene, toluene, xylene, methanol, ethanol and ethyl acetate, in the presence of an ordinary reducing catalyst such as Raney nickel catalysts and palladium-carrying carbon under atmospheric pressure to a hydrogen pressure of 20 g/cm.sup.2 at a temperature of from 20.degree. C. to 100.degree. C.

The reaction of formula (4) may be carried out without solvent or in an inert solvent such as acetone, dioxane, benzene and toluene in the presence of an acid catalyst such as HCl, H.sub.2 SO.sub.4 and Amberlist-15 by heating to a temperature of from 40.degree. C. to 120.degree. C.

Among the compounds of general formula [II], those compounds represented by general formula [II-2]: ##STR187## wherein R.sup.11, R.sup.12, and A are as defined above can be produced not only by the reaction of formula (1), but also by reaction as shown by formula (5).

[III]+:CCl.sub.2 .fwdarw.[II-2] (5) The reaction of formula (5) can be carried out by agitating a mixture of compound [III], chloroform, and NaOH or KOH without solvent or in an aqueous medium in the presence of a quaternary ammonium salt such as benzyltrimethyl ammonium chloride.

At the end of reaction, the end product can be recovered by a conventional method as shown in the following examples.

For typical ones of compounds Ar-OH used in the above preparation procedure, their typical synthesis is exemplified in Table 12 of Japanese Patent Application No. 61-177858 (WO 87/00840). Those compounds which are not exemplified in this Application may also be synthesized by a similar procedure.

A 50-ml two-necked round-bottomed flask equipped with a dropping funnel was charged with 0.64 grams of sodium hydride and washed twice with n-hexane. To the flask were added dropwise 2.0 grams of 3-methyl-2,3-dihydro-6-benzofuranol and 10 ml of dimethylformamide at room temperature. After evolution of hydrogen ceased, 2.1 grams of 2-chloro-5-nitropyridine in 10 ml of dimethylformamide was added dropwise. The mixture was agitated for 3 hours at room temperature. After water was added to the reaction mixture, the product was extracted with ethyl acetate, washed with water, and then dried over anhydrous magnesium sulfate. The extracting solvent was distilled off to leave a residue, which was purified by chromatography through a silica gel column using a 4/1 n-hexane/ethyl acetate mixture, obtaining 3.0 grams of brown crystals (yield 83%).
