Abstract (en)

[origin: WO2019007828A1] The present invention relates to a method for electrochemically producing arylalkyl carbonates or diaryl carbonates, which is characterized in that compounds of formula (1) R1-OH, wherein the radical R1 is an alkyl radical, preferably a radical from the range: C1 to C6alkyl, preferably methyl or ethyl, isopropyl or tert-butyl or cycloalkyl, preferably cyclohexyl, with a compound of formula (2) R2-OH, wherein the radical R2 is an aryl radical, preferably tert-butylphenyl, cumylphenyl, naphthyl or phenyl, particularly preferably is a phenyl radical, are subjected to anodic reaction with CO at an electrode with gold as heterogeneous electrocatalyst, and also the use thereof for producing polycarbonates.
