A series of phenolic bio‐oil components were selectively hydrodearomatized by palladium on carbon into the corresponding ketones or alcohols in excellent yields using polymethylhydrosiloxane and water as reducing agent. The selectivity of the reaction was governed by the water concentration where selectivity to alcohol was favoured at higher water concentrations. As phenolic bio‐oil examples cardanol and beech wood tar creosote were studied as substrate to the developed reaction conditions. Cardanol was hydrodearomatized into 3‐pentadecylcyclohexanone in excellent yield. From beech wood tar creosote, a mixture of cyclohexanols was produced. No hydrodeoxygenation occurred, suggesting the applicability of the reported method for the production of ketone‐alcohol oil from biomass.

使用PMHS和H2O作为氢源，将含苯酚的生物油进行延性Pd催化的加氢脱芳香化反应成酮或醇

使用聚甲基氢硅氧烷和水作为还原剂，通过钯/碳选择性地将一系列酚类生物油组分加氢脱芳香化为相应的酮或醇，产率很高。反应的选择性取决于水的浓度，其中较高的水浓度有利于醇的选择性。作为酚类生物油的实例，研究了腰果酚和山毛榉木焦油杂酚油作为开发的反应条件的底物。腰果酚以优异的产率加氢脱芳基化为3-十五烷基环己酮。从山毛榉木焦油杂酚油中，制得环己醇的混合物。没有发生加氢脱氧反应，表明该报道的方法可用于由生物质生产酮醇油。
