for the hydrogenation of carbocyclic and heterocyclic aromatic compounds at room temperature and 1 atm of hydrogen pressure. The effect of substitution on the benzene ring was examined in a variety of derivatives, including those with alkyl, hydroxy, alkoxy, aryloxy, carboxy, amino, nitro, acyl, chloro, or functionalized alkyl groups. Reduction of carbonyl functions of aromatic aldehydes and ketones occurred
石墨上的铑(Rh / Gr,C 24 Rh)是通过无水三氯化铑与石墨钾(C 8 K,3当量)反应制得的,并用作在室温下氢化碳环和杂环芳族化合物的非均相催化剂。氢气压力为1大气压。在多种衍生物中检查了取代对苯环的影响,包括具有烷基,羟基,烷氧基,芳氧基,羧基,氨基,硝基,酰基,氯代或官能化烷基的那些衍生物。芳族醛和酮的羰基官能团还原发生在苄基CO键完全或部分断裂的情况下;这种裂解也发生在苄醇和酯的氢化中。 芳香族化合物-石墨-非均相催化-加氢-铑
