Abstract

The invention belongs to the technical field of organic synthesis and particularly provides a method for synthesizing (trifluoromethoxy) anisidine formylhydrazine with a little amount of hydrazine hydrate as reactants, inexpensive organic solvents not mutually dissolving with water as reaction system solvents and phase transfer catalysts as catalysts. The synthetic method quickens reaction, improves product quality and yield, avoids highly virulent hydrazine hydrate pollution, and has the advantages of being high in yield, small in environment pollution and low in cost.

Description

technical field

[0001] The invention belongs to the technical field of organic synthesis, and relates to a synthesis technology of a pesticide intermediate, in particular to a synthesis method of metaflumizone intermediate p-trifluoromethoxyanilinoformohydrazide. Background technique

[0002] The English name of metaflumizone is metaflumizone, chemical name: (E+Z)-2-[2-(4-cyanophenyl)-1-[3-(trifluoromethyl)phenyl]ethylene] -N-[4-(trifluoromethoxy)phenyl]-hydrazine oxalyl, its pure product is white solid powder.

[0003] Metaflumizone is a semicarbazone insecticide with a unique mechanism of action. The drug mainly enters into the body of the pest to kill the pest through gastric poisoning, and the contact effect is small and has no systemic effect. The drug has a good control effect on the target pests and larvae of all ages. After the insects feed, the drug enters the insect body and blocks the sodium ion channel on the axon membrane of the pest neurons through a unique m...
