• Synthesis and catalytic properties of neutral and cationic rhodium- and iridium-containing carbosilane dendrimers

  The reaction of phosphanyl-terminated carbosilane dendrimers containing only one phosphorus ligand per arm with [MCl(cod)]2 (M = Rh, Ir; cod = cycloocta-1,5-diene) resulted in the grafting of MCl(cod) moieties on the surface of the dendrimer. However, dendrimers displaying two phosphorus ligands per arm gave very unstable species which were not isolated. On the other hand, the last group of dendrimers reacted with [MCl(cod)]2, in the presence of silver salts, to afford cationic dendrimers in which a metal fragment is attached simultaneously to both phosphorus atoms of the same arm. The substitution of cod with 1,1′-bis(diphenylphosphino)ferrocene (dppf) in one example of the latter group yielded a bimetallic Rh/Fe layer-containing dendrimer. The new metallodendrimers were tested as catalysts in the hydrogenation of 1-hexene.

  每臂仅含有一个磷配体的膦基封端的碳硅烷树枝状聚合物与 [MCl(cod)]2 的反应 （M = Rh、Ir；cod = 环辛-1,5-二烯）导致 MCl(cod) 部分接枝到树枝状聚合物的表面上。然而，每臂展示两个磷配体的树枝状聚合物给出了非常不稳定的物种，该物种未被分离。另一方面，最后一组树枝状聚合物在银盐存在下与[MCl(cod)]2反应，得到阳离子树枝状聚合物，其中金属片段同时连接到同一臂的两个磷原子上。在后一组的一个例子中，用 1,1'-双（二苯基膦）二茂铁（dppf）取代 cod 产生了含双金属 Rh/Fe 层的树枝状聚合物。新的金属树枝状聚合物作为 1-己烯氢化催化剂进行了测试。

  The reaction of a series of phosphanyl-terminated carbosilane dendrimers displaying only one phosphorus ligand per arm with [RuCl2(p-cymene)]2 resulted in the grafting of RuCl(p-cymene) moieties on the periphery of the dendrimer. In these species, the chloride ligand is easily displaced by the organic bases pyridine, 4-cyanopyridine and 4,4′-bipyridine to afford new cationic metallodendrimers. NMR studies have confirmed the chirality of the ruthenium centre. The species containing 4,4′-bipyridine reacts through the uncoordinated pyridyl nitrogen with a new equivalent of [RuCl2(p-cymene)]2 or [RhCl(CO)2]2 to lead to homo- or hetero-bimetallic layer-containing dendrimeric systems. The ruthenodendrimers were tested as catalysts in the transfer hydrogenation of cyclohexanone by propan-2-ol and their activity compared with that of some analogous mononuclear ruthenium(II) complexes.

  一系列磷烷基封端的碳硅烷树枝状分子（每臂仅有一个磷配体）与[RuCl2(p-cymene)]2的反应结果是，RuCl(p-cymene)部分接枝在树枝状分子外围。在这些物种中，氯化物配体很容易被吡啶、4-氰基吡啶和4,4′-联吡啶等有机碱置换，从而形成新的阳离子金属树枝状分子。核磁共振研究证实了钌中心的旋光性。含有4,4′-联吡啶的物种通过未配位的吡啶氮与新的等效物[RuCl2(p-cymene)]2或[RhCl(CO)2]2发生反应，从而形成含有单金属或双金属层的树枝状分子系统。钌树枝状分子作为催化剂，在丙烷-2-醇对环己酮的转移氢化反应中进行了测试，并与一些类似单核钌（II）配合物的活性进行了比较。

  The reaction of the carbosilane dendrimers Si(CH2CH2SiMe3-nCln)(4) (n = 1,2) with LiCH2PPh2 afforded the new phosphino-terminated dendrimers Si(CH2CH2SiMe2CH2PPh2)(4) (1) and Si(CH2CH2SiMe(CH2PPh2)(2))(4) (2). By treatment of 1 and 2 with ClAu(tht), the gold-containing dendrimers Si(CH2CH2SiMe2CH2PPh2AuCl)(4) (3) and Si(CH2CH2SiMe(CH2PPh2AuCl)(2))(4) (4) were obtained, which in turn, reacted with (PPh4)(2)[Fe-3(CO)(11)] to give the first metal-cluster-containing dendrimers reported so far: (PPh4)(4)[Si(CH2CH2SiMe2CH2PPh2 AuFe3(CO)(11)})(4)] (5) and (PPh4)(8)[Si(CH2CH2SiMe(CH2PPh2 AuFe3(CO)(11)})(2))(4)] (6).

  The first series of peripherally silver phosphorus functionalized dendrimers have been obtained selectively using mono- or diphosphine-terminated carbosilane dendrimers and silver triflate. With the first kind of functionalized dendrimers, simple phosphine-Ag(OTf) terminal groups are formed, whereas in the second case, only one silver ion appears bonded to each diphosphine moiety (chelate form).
