Abstract

A találmány tárgya eljárás (I) általános képletű malonsavészterekelőállítására. Az (I) általános képletben R jelentése C1-C10-alkil-, C3-C10-alkenil- vagy aril-C1-C4-alkilcsoport. A vegyületeket úgy állítják elő, hogy a malonsavvalamely alkálifémsóját víz és fázistranszfer-katalizátor jelenlétébenegy (II) általános képletű R-X (II) halogeniddel, amelynek képletében R jelentése a fenti és X klór-,bróm- vagy jódatomot jelent, reagáltatják.
