Process for the preparation of Esters or Ester - amide acids (Phosphoric tiono) (thiol) (Phosphoric) 4 - Hydro - xiquinoleinas replaced

摘要

Process for the production of Esters or Ester - amide acids (Phosphoric tiono) (thiol) (4 - hidroxiquinoleinas substituted phosphonic) of formula (i), in which x is Oxygen or sulfur, R2, and R4 are alcohilo c1-4 and R1, R3 and R5 can be several types radical.Involves the reaction of a compound of formula (ii) with a compound of formula (iii), in which R1 - R5 x y have the same meaning as in formula (i). The reaction is carried out in an Inert Organic Solvent, in the presence of an organic or inorganic base as fiajdor Agent and hydrochloric acid at a temperature between atmosphere and reflux.These compounds have applications in agricultuta by acaricide and insecticide activity.
