An efficient and practical arene hydrogenation procedure based on the use of heterogeneous platinum group catalysts has been developed. Rh/C is the most effective catalyst for the hydrogenation of the aromatic ring, which can be conducted in iPrOH under neutral conditions and at ordinary to medium H2 pressures (<10 atm). A variety of arenes such as alkylbenzenes, benzoic acids, pyridines, furans, are
已经开发了基于使用异质铂族催化剂的有效和实用的芳烃加氢方法。Rh / C是最有效的芳环加氢催化剂,可以在中性条件下,在常压至中等H 2压力(<10 atm)下在i PrOH中进行。将各种芳烃(如烷基苯,苯甲酸,吡啶,呋喃)以良好或极好的收率氢化成相应的环己基和杂环化合物。Ru / C的使用比Rh / C便宜,它为氢化包括苯酚在内的芳烃提供了一种有效而实用的方法。在简单过滤后,两种催化剂都可以重复使用数次,而催化活性没有任何重大损失。
