application of ruthenium nanoparticles (RuNPs) stabilized by the N-heterocyclic carbenes (NHC) N,N′-di(tert-butyl)imidazol-2-ylidene (ItBu) and 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene IPr as catalysts in the hydrogenation of several substrates is reported under various reaction conditions (solvent, substrate concentration, substrate/metal ratio, temperature). The RuNHC nanoparticles are active
N-杂环卡宾(NHC)N,N'-二(叔丁基)咪唑-2-亚烷基(I t Bu)和1,3-双(2,6- )稳定的钌纳米颗粒(RuNPs)的应用在各种反应条件(溶剂,底物浓度,底物/金属比,温度)下,报道了在几种底物加氢中作为催化剂的二异丙基苯基)亚咪唑-2-亚烷基IPr。RuNHC纳米粒子是芳烃加氢中的活性催化剂,并表现出有趣的配体效应,RuIPr NPs通常比RuI t Bu具有更高的活性。
