Abstract
Process for obtaining 3,4-disubstituted 2 (5ii) -furanones of formula I **(See formula)** wherein R is C 1 -alkyl, phenyl, optionally substituted one or more times by phenyl, optionally halogenated, halogen, NO2, Cf3 CN, R1 and/or OR2, or optionally substituted by chlorine, X means Cn or COOR2 and R2 means alkyl with 1 to 4 carbon atoms, characterized in that a compound of formula II R1-CO-Cl-OCOCH3 (II) Where R1 has the meaning indicated above, it is reacted in a polar solvent, in the presence of a basic condensation medium, with a compound of formula III X-CH2-COOR2 (III) where X and R2 have the meaning indicated above.
