We present the preparation and investigation of a fluorine-free surface-active bis-N-heterocyclic carbene (NHC) platinum(II) complex - trans-[Pt(mPEGCIm)Cl] - for interface-enhanced supported ionic liquid phase (SILP) catalysis within a group of (mPEG)-substituted ionic liquids (ILs) ([(mPEG)Im][A] ILs). The complex was characterized by means of single-crystal X-ray diffraction (scXRD) analysis and multinuclear (H, C, Pt) NMR spectroscopy, indicating the presence of two almost equimolar syn-anti-rotamers of the square-planar complex in solution. Angle-resolved X-ray photoelectron spectroscopy (ARXPS) revealed pronounced interface-accumulation of trans-[Pt(mPEGCIm)Cl] in IL solutions of [(mPEG)Im][A] (A=I and PF ).
我们展示了一种无氟表面活性双-N-杂环卡宾（NHC）铂（II）配合物——反式-[Pt(mPEGCIm)Cl]——的制备和研究，用于在一组（mPEG）取代的离子液体（ILs）（[(mPEG)Im][A] ILs）中进行界面增强的负载离子液体相（SILP）催化。该配合物通过单晶X射线衍射（scXRD）分析和多核（H、C、Pt）核磁共振光谱进行了表征，表明溶液中平面正方形配合物存在两种几乎等摩尔的顺-反旋转异构体。角分辨X射线光电子能谱（ARXPS）显示反式-[Pt(mPEGCIm)Cl]在[(mPEG)Im][A]（A = I和PF）的IL溶液中存在明显的界面积累。
