The invention relates to oximes, in particular, a method for producing ethers of oximes (er) of a common yomuly. C AND-C (X) N-0-CH, -CH (OC) (OR), where P and R, are hydrogen or halogen; 1C and RZ,, alkylene; X is a fluorinated C-C, -aluch, used as antidotes for the phytotoxic effect of herbicides on cultivated plants. The goal is to create more active compounds of the specified class. Synthesis of EO compounds is carried out from the salt of the oxime of the general formula R, where R is indicated above; M is an alkali metal cation, and a haloacetal of the general formula H1-CH 2 -CH (OR3) (OR), where R and R are as defined above; Hal is halogen, in dimethyl sulfoxide environment at 60-70 ° C for 4 hours and 30, resistance to fungal damage is increased, the germination of weakly germinating seeds is less inhibited than the known compounds, at a flow rate of 0.4 kg / ha OE, this same antidote effect, as known cyanoxime at the rate of consumption. 1.5 kg / ha when treating plants with herbicides of the row of acetanilide. DLgo toxicity 4560 mg / kg. 14 tabl CO with |
