摘要
设计合成和表征了新型叠氮基官能团化的SIPr(2,6-diisopropylphenyl]imidazolin-2-ylidene)氮杂卡宾铜配合物.这种氮杂卡宾铜配合物既可作为反应底物又可作为催化剂进行自催化的叠氮炔烃3+2环加成反应(CuAAC).通过这种配合物与炔烃的简单自催化反应,在常温常压条件下合成出了一种新型的基于氮杂卡宾铜配合物的超分枝'聚合物',并通过固体核磁、红外光谱、元素分析、原子吸收光谱和X射线光电子能谱对其进行了完整的表征.
Novel azide-tagged copper (I) complex of N-Heterocycic carbenes (NHCs) analogues to the well known bis [ 2,6-diisopropylphenyl ] imidazolin-2-ylidene (SIPr) was synthesized and characterized. The complex was able to act as catalyst and substrate in a model copper-catalyzed azied-alkyne cycloaddi- tion ( CuAAC ) reaction with tris (4-ethynylphenyl) amine, yielding novel hyperbranched NHC-Cu ( I ) complex-based "click polymers" via the methodology of self-catalyzed click chemistry.
