nanoparticles, either formed in situ stabilized by 1,6-bis(diphenylphosphino)hexane or polyethylene glycol (PEG), or preformed stabilized by PEG, are excellent catalysts for the cross-coupling of aryl Grignard reagents with primary and secondary alkyl halides bearing beta-hydrogens and they also prove effective in a tandem cyclization/cross-coupling reaction.
铁纳米颗粒,无论是通过1,6-双(二苯基膦基)己烷或聚乙二醇(PEG)原位形成,还是由PEG稳定形成,都是芳基格氏试剂与带有伯烷基卤和仲烷基卤的交叉偶联的极佳催化剂。 β-氢,并且它们在串联环化/交叉偶联反应中也证明是有效的。
