Pressure-Enhanced C-H Bond Activation in Chloromethane Platinum(II) Complexes
The nature of the interaction between chloromethanes CH4-nCln and Pt(II) complexes has been studied by high-pressure X-ray diffraction and infrared spectroscopy in combination with DFT calculations. In case of electron rich complexes such as d(8)-Pt(btz-N,N ‘)(phenyl)L with L = phenyl, Cl, Br and btz = 2,2 ‘-Bi-5,6-dihydro-4H-1,3-thiazine stable chloroform adducts with bridging hydrogen atoms in the eta(1)(C-H)Pt moieties were isolated which display highly activated C-H bonds. This activation is a consequence of a pronounced Pt(d(z2))->sigma*(C-H) back donation and is signaled by large red-shifts of the isolated nu(is)(C-H) stretching modes. The extent of the C-H bond activation and covalent Pt-H bond formation in the eta(1)(C-H)Pt moieties is thereby controlled by (i) the sigma/pi donor capabilities of the ligands L, (ii) the orientation of the coordinating C-H bond with regard to the Pt(d(z2)) orbital and (iii) the applied pressure.
The proportionality constant is the rate constant for the particular unimolecular reaction. You can get involved in discussing the latest developments in this exciting area about 7689-03-4. Recommanded Product: 7689-03-4.
