Abstract:
(EN) 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.
(FR) La présente invention concerne un procédé de production électrochimique de carbonates de diaryle ou de carbonates d’arylalkyle. Le procédé est caractérisé en ce que des composés de la formule (1) R1-OH, le radical R1 étant un radical alkyle, de préférence un radical de la série : alkyle en C1 à C6, de préférence un méthyle ou éthyle, isopropyle ou tert-butyle, ou cycloalkyle, de préférence cyclohexyle, est mis à réagir avec un composé de la formule (2) R2-OH, R2 représentant un groupe aryle, de préférence un tert-butylphényle, cumylphényle, naphtyle ou phényle, de manière particulièrement préférée un radical phényle, au niveau d’une électrode en présence d’or utilisé comme électrocatalyseur hétérogène, la réaction se faisant anodiquement avec du CO, ainsi que leur utilisation dans la production de polycarbonates.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur elektrochemischen Herstellung von Arylalkylcarbonaten oder Diarylcarbonaten, welches dadurch gekennzeichnet ist, dass Verbindungen der Formel (1) R1-OH wobei der Rest R1 einen Alkylrest bedeutet, bevorzugt ein Rest aus der Reihe: C1- bis C6- Alkyl, bevorzugt Methyl-, oder Ethyl-, iso-Propyl oder tert-Butyl, oder Cycloalkyl, bevorzugt Cyclohexyl, mit einer Verbindung der Formel (2) R2-OH wobei der Rest R2 einen Arylrest bedeutet, bevorzugt Tert-butylphenyl-, Cumylphenyl-, Naphthyl- oder Phenyl-, besonders bevorzugt einen Phenylrest bedeutet, an einer Elektrode mit Gold als heterogenem Elektrokatalysator anodisch mit CO umgesetzt wird, sowie deren Verwendung zur Herstellung von Polycarbonaten.
