Abstract

Abstract : Preparation of highly ordered mesoporous polymer supported gold(i ) catalyst as efficient and recyclable catalysts for construction of carbon–hetero bond . Abstract : A series of novel heterogeneous gold(i ) catalysts were synthesized by immobilizing gold(i ) complexes on ordered mesoporous polymer FDU-15 and characterized by XRD, N2 adsorption–desorption, FT-IR, TEM, EDS, etc. The catalytic activities of these catalysts were evaluated by the amination reactions of allylic alcohols. Among the catalysts investigated, FDU-( p -CF3 Ph)2 PAuCl (3d ) was identified as the most efficient catalyst. Compared to the homogeneous catalyst, the enhanced catalytic activity of the heterogeneous gold(i ) catalyst is closely related to the mesoporous structure of FDU-15. The catalytic system was suitable for a broad range of substrates and can be easily recovered and recycled at least twelve times without significant loss of catalytic activity. In addition, the catalytic performance of3d was further examined for intramolecular cyclization for the synthesis of heterocyclic compounds.
