METHOD FOR PRODUCING 5-ALKOXY (OR 5-AROXY)-2,3-DIHYDROFURAN-2-ONES

摘要

The invention relates to a method for producing a compound of the general formula (I), where 1,2-bisketenes of the general formula (II) are reacted with an alcohol of the general formula (III) R''-OH in the presence of a Cu-containing coordination catalyst, where R, R' and R'' independently of each other represent a linear or branched aliphatic, unsaturated and/or aromatic C1-C30 hydrocarbon rest which can contain heteroatoms and/or be substituted.
