    structures have been determined by single-crystal X-ray analysis. The use of these complexes as catalysts for the Suzuki and Buchwald–Hartwig amination of aryl chlorides was examined. Compound 2 was found to be very efficient for these reactions. Typically, using 0.5–1 mol% of catalyst in the presence of 3 equivalents of KtOBu as base in PEG-400 [poly(ethylene glycol-400)] at 120 °C provided coupling
    摘要合成了环palpalated二茂铁吡啶1-2的两个空气稳定的卡宾加合物,并通过元素分析,IR,ESI-MS,1H和13C NMR对其进行了表征。此外,它们的详细结构已通过单晶X射线分析确定。检查了这些络合物作为Suzuki和Buchwald-Hartwig芳基化物胺化反应的催化剂。发现化合物2对于这些反应非常有效。通常,在120°C下在PEG-400 [聚(乙二醇-400)]中存在3当量的KtOBu作为碱的情况下,使用0.5-1 mol%的催化剂可提供优异的收率。此外,2 / PEG-400系统可以循环使用三遍。

    Three N-heterocyclic carbene (NHC) adducts of cyclopalladated ferrocenylchloropyrimidine, 2–4 [PdCl[(η5-C5H5)]Fe[(η5-C5H3)-N2C4H2-Cl]}(NHCs)] have been prepared by reaction of the chloride-bridged palladacyclic dimer 1 [PdCl[(η5-C5H5)]Fe[(η5-C5H3)-N2C4H2-Cl]}]2 with the corresponding imidazolium salts. These complexes were characterized by elemental analysis, IR, ESI–MS and NMR. The use of these complexes as catalysts for the Sonogashira reaction was examined. Complex 4 proved to be an efficient catalyst for the Sonogashira reaction of aryl bromides and some activated aryl chlorides under copper- and amine-free conditions. Typically, using 0.1–2 mol % of catalyst in the presence of 1.5 equivalents of CsOAc as base in dimethylacetamide at 120 °C provided coupling products in good yields.

    different platinum(II)-bis-NHC-complexes in the hydrosilylation of alkenes have been investigated and compared with the catalytic activity of the Karstedt catalyst and of a highly active platinum(0)-NHC-complex. It is shown that a fine-tuning of the catalytic activity of the platinum(II)-bis-NHC-complexes is possible.
