Paragraph 0029; 0030, (2017/09/02)
The invention discloses a method of preparing intermediates of fufu grass alkone, including: (1) to between three happens b nitrile and benzene acetyl chloride as the starting material, tertiary butyl alcohol sodium and organic solvent in the presence of the intermediate obtained by reaction of (3 - trifluoromethyl-phenyl) - benzyl carbonyl - b nitriles; (2) intermediate (3 - trifluoromethyl-phenyl) - benzyl carbonyl - acetonitrile and glacial acetic acid by the reaction of bromine fufu grass alkone intermediate 2 - phenyl - 3 - oxo - 4 - (3 - trifluoromethyl-phenyl) - 5 - amino - 2, 3 - dihydrofuran. Preparation method of this invention mild reaction, after treatment is simple, safety and environmental protection, especially few by-products, the product has high purity, and thus is suitable for industrial production.

Paragraph 0024, (2016/10/10)
The invention discloses an efficient method of producing herbicide [...], to trifluoromethyl benzene b nitrile and benzene acetic acid ethyl ester as the main raw material, the claisen condensation, cyclization under in an acidic solvent, methylation three steps [...] the target product can be obtained. The present invention has higher safety, for reaction and purification conditions is relatively low, it is relatively easy to separate, and is not easy to generate discharge of waste acid, the solvent can be recycled, the production yield is higher. This method is more suitable for the industrial production of [...], [...] is more favorable for the wide application of efficient herbicide. (by machine translation)
Process for preparing substituted amino herbicides

, (2008/06/13)
Processes for alkylating certain 3-oxo-4-substituted phenyl-5-amino-2,3-dihydrofurans and 2,3-dihydrothiophenes. The process effects replacement of the 5-amino group with a new amino group having the desired substitution. The products are useful as herbicides.
