摘要：
A series of platinum(II) dihalide pyridine complexes bearing chiral C-2-symmetric N-heterocyclic carbene (NHC) ligands [Pt(NHC*)(Py)(Hal)(2)] was synthesized in a one-pot procedure and characterized by NMR spectroscopy and single crystal X-ray diffraction (SC-XRD). The complexes were tested for the asymmetric cycloisomerization of enynol into bicyclo[3.1.0]-hexanone and feature an excellent catalytic activity at room temperature along with a modest enantiomeric induction (up to 39% ee).
