Embodiment 1

[0043] The synthesis of embodiment 1 compound A-1:

[0044]

[0045] In the 1000 milliliter there-necked flask, add 300 milliliters of acetic anhydride, 200 milliliters of acetic acid, 15.8 grams (0.1mol) of 2,2-difluorobenzo[d][1,3]dioxane shown in formula M-01, cooling To 10°C, slowly add dropwise a mixture of 9.69 grams (0.1mol) of 65% nitric acid and 20.6 grams of 98% sulfuric acid, and keep the reaction at 10°C for 90 minutes, add water and dichloromethane to separate the liquid, and wash the organic layer with water until neutral , concentrated to dryness, separated by silica gel column chromatography, eluting with petroleum ether:ethyl acetate=10:1 (volume ratio), to obtain 2,2-difluoro-4-nitrobenzo[ d] [1,3]dioxane 5.8 g, yield 28.57%.

[0046] The 2,2-difluoro-4-nitrobenzo[d][1,3]dioxane represented by the obtained M-02 was detected by mass spectrometry, and the m / e of the product was obtained: 203.

[0047] Add 200 milliliters of methanol, 5 grams of 5% Pd / C (dr...

Embodiment 2

[0057] Embodiment 2 Synthesis of other part of compounds of the present invention

[0058] Referring to the synthesis of compound A-1, just replace M-01 and M-05 according to the needs, synthesize the following compounds, and perform mass spectrometry detection on the synthesized compounds. The results are shown in the following table:

[0059]

[0060]

[0061]

Embodiment 3

[0062] The preparation of embodiment 3 wettable powders:

[0063] A total of 18 kinds of wettable powders were prepared, and the components of the prepared wettable powders are listed below, wherein the percentages are weight percentages.

[0064]

[0065]

[0066] The preparation method of wettable powder is illustrated as follows with the code name of wettable powder KS-1:

[0067] Active ingredient A-1 of 25% by weight, sodium lauryl sulfate of 2% by weight, sodium lignosulfonate of 3% by weight, tetrabutylammonium bromide of 0.2% by weight, naphthalenesulfonic acid of 2% by weight The formaldehyde condensate and 67.8% of light calcium carbonate are fully mixed and pulverized by an ultra-fine pulverizer to obtain a 25% wettable powder.

Abstract

The invention especially relates to a bactericide, belonging to the technical field of agriculture. The bactericide contains a compound as shown in a formula (A) which is described in the specification. In the formula (A), X1 and X2 are selected from fluorine; and R1, R2 are selected from a group consisting of a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, a hexyl group and a phenyl group.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a fungicide and its application. Background technique [0002] Plant diseases cause huge losses to agriculture, resulting in a large reduction in crop yields. The use of fungicides is an economical and effective method to control plant diseases, so it is of great significance to develop new and efficient agricultural fungicides. Contents of the invention [0003] The invention provides a compound shown in formula (A): [0004] [0005] where X 1 , X 2 selected from fluorine, chlorine, and X 1 , X 2 Can be the same or different; R 1 , R 2 It is selected from an aliphatic alkyl group having 1 to 20 carbon atoms, and an aryl group consisting of carbon and hydrogen having 6 to 20 carbon atoms. [0006] In another aspect of the present invention, in formula (A), X 1 , X 2 , all selected from F. [0007] In another aspect of the present invention, in formula (A), ...
