[0168] Example 1: 3-(2,6-dimethylphenyl)-6-(1-ethyl-5-hydroxyl-1H-pyrazole-4-carbonyl)-1-methyl-1H-benzo[ c] Synthesis of [1,2,6]thiadiazin-4(3H)-one 2,2-dioxide

[0169]

[0170] Step 1: Synthesis of 4-nitroisophthalic acid

[0171]

[0172] At room temperature, potassium hydroxide (12.39g, 662mmol), water (400mL) and 2-nitro-5-methylbenzoic acid (40g, 220mmol) were added to a 1L reaction flask, and heated to 90°C until the solid was completely After dissolving, potassium permanganate (104.69 g, 662 mmol) was added in batches, and the stirring reaction was continued at 90° C. for 3 hours. Filter the reaction solution while it is hot, rinse the filter residue with water (50mL×2), wait until the temperature of the obtained liquid is cooled to room temperature, adjust the pH value of the liquid to make it pH=1, stir at 0°C for 30 minutes, filter, and dry the filter cake , to obtain 43g of white solid, yield 92%.

Description

technical field [0001] The present invention relates to the field of pesticides, in particular, the present invention relates to a benzothiadiazine derivative and a preparation method thereof, a composition containing the derivative, and the application of the derivative and the composition in controlling weeds . Background technique [0002] WO2017140612A1 and CN104557739A disclose the herbicidal activity of 2,4-quinazolinedione compounds. WO9742185 discloses that benzoxathiodioxide has certain herbicidal activity. The benzothiadiazine dioxide involved in the present invention has not been The prior art has been published. [0003] The active ingredients known from the documents cited above have disadvantages in use such as (a) no or only insufficient herbicidal action on weed plants, (b) excessive spectrum of weed plants to be controlled. Narrow or (c) too low selectivity in useful plant crops. [0004] Therefore, there is a need to provide chemically active ingredients...
