[摘要]：Polyamine dendrimer-encapsulated Pd2+ catalysts were prepared by complexation of PdCl2 with internal tertiary amino groups of the dendrimer. The fifth-generation Pd2+ dendrimer catalyst showed cooperative catalysis between Pd2+ species and the internal nanocavity consisting of regularly arranged tertiary amino groups to promote the intramolecular cyclization of gamma-acetylenic acids efficiently. |
