Direct functionalization of alkanes by oxidation of C–H bonds to form alcohols under mild conditions is a challenge for synthetic chemistry. Most alkanes contain a large number of C–H bonds that present difficulties for selectivity, and the oxidants employed often result in overoxidation. Here we describe a divanadium-substitutedphosphotungstate that catalyses the stereo- and regioselective hydroxylation

Valorization of lignin is essential for the economics of future lignocellulosic biorefineries. Lignin is converted into novel polymerbuildingblocks through four steps: catalytic hydroprocessing of softwood to form 4‐alkylguaiacols, their conversion into 4‐alkylcyclohexanols, followed by dehydrogenation to form cyclohexanones, and Baeyer–Villiger oxidation to give caprolactones. The formation of alkylated
木质素的增价对于未来木质纤维素生物精炼厂的经济性至关重要。木质素通过以下四个步骤转化为新型的聚合物结构单元:针叶木的催化加氢处理形成4-烷基愈创木酚,将其转化为4-烷基环己醇,然后脱氢形成环己酮,以及Baeyer-Villiger氧化生成己内酯。烷基化环己醇的形成是该系列中最困难的步骤之一。在CeO 2或ZrO 2上存在镍的液相过程本文证明了催化剂可产生最高的环己醇收率。与4-烷基愈创木酚的催化反应遵循两条平行的途径,且速率相近:1)环加氢形成相应的烷基化2-甲氧基环己醇,以及2)脱甲氧基化形成4-烷基苯酚。尽管随后的苯酚向环己醇的转化速度很快,但从2-甲氧基环己醇中除去甲氧基的速率受到限制。总的来说,这最后一个反应是限速步骤,需要足够的温度(> 250°C)才能克服能垒。Ni / CeO 2的底物反应性(相对于烷基链的类型)和反应速率的催化剂特性(镍负载量和镍粒度)的细节已详细报道。催化剂。最好的Ni

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
