    (cyclotrimerization vs. dimerization), [RuCl2(p-cymene)]2/PR3 has been developed for the catalytic dimerization of terminal alkynes. Bulky and basic phosphine derivatives, PCy3 and P(i-Pr)3, were used with [RuCl2(p-cymene)]2 and excess of terminal alkyne to in situ formation of vinylidenic intermediates which are active towards dimerization reactions. Effect of phosphine/ruthenium ratio has been investigated
    在这项研究中,已开发出一种实用且廉价的可转换催化系统(环三聚与二聚)[RuCl 2(对苯甲基)] 2 / PR 3用于末端炔烃的催化二聚。大型和碱性膦衍生物PCy 3和P(i- Pr)3与[RuCl 2(对-异丙基)] 2一起使用和过量的末端炔烃就地形成对二聚反应有活性的亚乙烯基中间体。已研究了膦/钌比的影响。进行了溶剂研究,发现甲苯是用于环三聚和二聚反应的最通用的溶剂。选择一组芳基和烷基乙炔作为底物,以研究底物性质对[RuCl 2(p-cymene)] 2 / PR 3催化的炔烃二聚反应的影响。总之,我们表明[RuCl 2(p-cymene)] 2 / PCy 3可以用作实用且廉价的催化体系,其对环三聚和二聚反应具有可切换的选择性。通过在这些反应中使用芳基乙炔衍生物,可以观察到最佳的区域选择性和产率结果。该催化体系是一种经济的方法,可以以优异的收率和选择性将芳基乙​​炔转化为相应的烯炔和芳烃衍生物。

    double hydrosilylated alkene, in which the two silicon moieties are connected at the same carbon atom, is obtained. The catalytic hydrosilylation of (TMS)CCH and PhSiH3 with [(Et2N)3U][BPh4] was found to proceed only at higher temperatures. Mechanistically, the key intermediate seems to be the uranium–hydride complex [(Et2N)2UH][BPh4], as evidenced by the lack of the dehydrogenative coupling of silanes

    hydroamination imine as the major product. However, when other bulkier amines were used (iPrNH2 or tBuNH2) both hydroamination isomeric imines Z and E were obtained. During the catalytic reaction, the E (kinetic) isomer is transformed into the most stable Z (thermodynamic) isomer. The unique reactivity of the alkyne (TMS) C identical to CH with the secondary amine Et2NH is remarkable because it afforded
    阳离子络合物[(Et2N)3U] [BPh4]中的三个辅助酰胺基部分具有很高的反应性,当用伯胺处理该络合物时,很容易被取代。[(Et2N)3U] [BPh4]与过量的tBuNH2的反应可以形成阳离子络合物[(tBuNH2)3(tBuNH)3U] [BPh4]。对络合物的X射线衍射研究表明,三个酰胺和三个胺配体以略微扭曲的八面体mer几何形状排列在阳离子金属中心周围。阳离子络合物在外部伯胺存在下与伯炔反应,主要提供意外的顺式二聚体,在某些情况下,同时获得加氢胺化产物。顺式二聚体的形成是通过金属-环丙基阳离子络合物的包膜异构化的结果。如氘标记实验所证实,在各种伯胺的存在下,与CH相同的大体积炔烃tBuC与阳离子铀络合物的反应中,区域选择性地获得了顺二聚体,一个三聚体和一个四聚体。三聚体和四聚体对应于炔烃分子连续插入到乙烯基CH键中,该乙烯基CH键反过来是庞大的叔丁基。在EtNH2存在下,(TM

    both chloride ligands and the hexahydride OsH6xant(PiPr2)2} (7), containing a κ2-P-binding diphosphine, is formed under 3 atm of hydrogen at 50 °C. Complex 7 releases a H2 molecule to yield the tetrahydride OsH4xant(PiPr2)2} (8), which can be also prepared by reaction of OsH6(PiPr3)2 (9) with xant(PiPr2)2.
