Phosphoric acid amide esters of general formula (I) (where R1, R2 and R3 = alkyl (1-5C); X = H or Cl) and the crotonic acid residue is in the cis configuration. Insecticides, acaricides and arachnicides. These compounds are more active than known compounds of similar structure and have a low phytotoxicity. This cis and trans isomers of formula (I) are separated by fractional distillation., the cis isomer having the higher boiling point. |
