diffraction. Several of these N-, N,N-, and N,N,N,-ligands have been grafted onto the surface of phosphorhydrazone dendrimers, from generation 1 to generation 3. The complexation ability of these monomers and dendrimers towards palladium(II) has been assayed. The corresponding complexes have been either isolated or prepared in situ. In both cases, the monomeric and dendritic complexes have been tested as catalysts
由苯酚官能化的吡啶、吡啶亚胺和联吡啶亚胺配体已被合成并表征,在许多情况下通过X射线衍射进行表征。从第 1 代到第 3 代,其中一些 N-、N,N- 和 N,N,N,-配体已接枝到磷腙树枝状聚合物的表面。这些单体和树枝状聚合物对钯 (II) 的络合能力已被化验。相应的配合物已被分离或原位制备。在这两种情况下,单体和树枝状配合物都已在 Heck 偶联和 Sonogashira 偶联中作为催化剂进行了测试。在某些情况下,观察到了积极的树枝状效应,即催化效率的增加与树枝状聚合物的生成成正比。
