Embodiment

[0036] Example: Synthesis of 5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitrobenzoic acid 2-(methoxycarbonyl)-1-phenylallyl ester (compound 1) :

[0037]

[0038] Add III-1 (11.6 grams, 0.032 moles, available from the market) and 150 milliliters of methylene chloride in a 250-ml reaction flask, stir, add oxalyl chloride (6.1 grams, 0.048 moles), 2 drops of DMF, stir at room temperature for 5 hours, concentrated to obtain 11.0 g of acid chloride, the appearance of which was yellow liquid (IV-1).

[0039]

[0040] Add V-1 (0.58 grams, 3.0 mmoles) in the reaction bottle of 50 milliliters, triethylamine (0.46 grams), 5 milliliters of dichloromethanes, drip IV-1 (1.2 grams, 3.2 millimoles) under stirring cooling The mixed solution of 10 ml of dichloromethane was added in about half an hour, and the reaction was carried out at room temperature for 6 hours. After the reaction was completed, 100 ml of dichloromethane and 50 ml of water were added to the reaction liquid, and the...

Abstract

The present invention belongs to the field of herbicide technology, and is especially 1, 2-disubstituted allyl aryloxy phthalate compounds and their application. The general expression of the compounds is shown. The compounds have herbicidal activity, especially on gramineous and broad-leaved weed, and may be used to control monocotylous weed effectively when it is applied before or after seeding emergence.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and relates to a 1,2-disubstituted allyl ester compound of aryloxybenzoic acid and an application thereof. Background technique [0002] Because weeds develop resistance to herbicides or compositions thereof over time, there is a continuing need to invent new and improved herbicidal compounds and compositions. In addition, considering economical and environmental factors, it is also necessary to invent herbicides with different mechanisms of action from existing herbicides. [0003] Certain aryl formic acid compounds have been reported as herbicides (DE2311638, EP0020052). However, the aryloxybenzoic acid 1,2-disubstituted allyl ester compound shown in the present invention has not been disclosed. Contents of the invention [0004] The invention provides a 1,2-disubstituted allyl ester compound of aryloxybenzoic acid, as shown in general formula I: [0005] [0006] in: [0007] X is ...
