合成了一种新的二铑双咪唑卡宾配合物，并用核磁共振谱和单晶X-射线衍射对其进行了表征。该配合物已被用作加氢反应的催化剂，显示出对支链醛的选择性。高压NMR光谱提供了证据表明，双核单元保持在催化条件下。
A new dirhodium(I) bisimidazolium-carbene complex has been obtained and fully characterized by means of NMR spectroscopy and single-crystal X-ray diffraction. The complex has been used as catalyst in hydroformylation reactions, showing selectivity on the branched aldehyde. High-pressure NMR spectroscopy provides evidence that the dinuclear unit is maintained under catalytic conditions.
