Hexa-ammonium functionalized Dendriphos ligands and mono-sulfonate functionalized metal complexes have been used as building blocks for the preparation of multimetallic dendritic assemblies. These metallodendrimers consist of a single metal centre surrounded by an oligocationic shell formed by the coordinated Dendriphos ligands and multiple associated anionic organometallic complexes.
Au-catalyzed hydroamination proceeds well for alkynes but not alkenes. We report gas-phase binding energies of alkenes and alkynes to a cationic Au center, which indicate that differences in binding are not the origin of the disparate chemical behavior. We further report the synthesis and characterization of 2-aminoalkylgold complexes, which would be the intermediates in a hypothetical Au-catalyzed hydroamination
Au 催化的氢化胺化对炔烃进行得很好,但对烯烃则不然。我们报告了烯烃和炔烃对阳离子 Au 中心的气相结合能,这表明结合的差异不是不同化学行为的根源。我们进一步报道了 2-氨基烷基金配合物的合成和表征,这将是假设的 Au 催化的苯乙烯加氢胺化的中间体。良好表征且可分离的配合物的反应性表明,2-氨基烷基金配合物的质子化或烷基化导致溶液和气相中的胺消除,表明金催化烯烃加氢胺化的失败源于非竞争性原型去氧步骤。我们分析了原型去饱和的可能过渡状态,
