3 results about "Triflumezopyrim" patented technology

The application belongs to the technical field of pesticide insecticide, and discloses an indazolic amide-containing insecticidal composition and application thereof. The insecticidal composition comprises active ingredient A and active ingredient B. The active ingredient A is indazolic amide, and the active ingredient B is any one of benzpyrimoxan, flupyrimin and triflumezopyrim. The mass ratio of the active ingredient A to the active ingredient B is 50:1-1:50. The insecticidal composition can significantly improve the control effect, the action mechanism is complementary, the insect pests can be quickly knocked down and the effective period is prolonged, the aphid population with resistance can be efficiently controlled, the development of single pesticide resistance can be delayed through compounding, the resistance risk is reduced, the control effect can be achieved at a low dose, and pesticide residues and environmental pollution are reduced.

Belonging to the technical field of organic synthesis, the invention relates to an efficient synthesis method of trifluoromethoxycarb, which comprises the following synthesis steps: taking a 3-methyl-2-butanone compound as a raw material for bromination to obtain 1-bromo-3-methylbutane-2-ketone; the method comprises the following steps: carrying out reductive amination on 1-bromine-3-methyl butane-2-ketone under the catalysis of transaminase to obtain (s)-1-bromine-3-methyl butane-2-amine; the (S)-1-bromine-3-methyl butane-2-amine is subjected to condensation with trifluoroethyl chloroformate, and 2, 2, 2-trifluoroethyl (s)-(1-bromine-3-methyl butane-2-yl) carbamate is obtained through condensation of the (S)-1-bromine-3-methyl butane-2-amine and trifluoroethyl chloroformate; the preparation method comprises the following steps: carrying out substitution reaction on 2, 2, 2, 2-trifluoroethyl (s)-(1-bromo-3-methylbutane-2-yl) carbamate and 4-methyl benzyl to obtain the trifluoromethoxycarb. The synthesis process is simple, efficient, green and safe.
