Platinum (II) complexes featuring chiral diphosphines and N-heterocyclic carbene ligands: synthesis and evaluation as cycloisomerization catalysts
No full textInternational audienceSquare-planar platinum(II) complexes that combine chiral diphosphines and NHC ligands have been obtained in high yields from (NHC)Pt(0)(dvtms) complexes, via an oxidative addition/ligand exchange sequence. The use of suitable carbeneâdiphosphine pairs allows axially chiral, configurationally stable platinum complexes to be isolated. The Pt(II) complexes have been evaluated as precatalysts for the cycloisomerization reaction of an allyl propargylamine derivative. Their catalytic properties have been examined as a function of structural variations on both the diphosphine and the NHC units. For axially chiral species possible epimerization pathways have been envisioned and the inversion barriers have been estimated through computational studie
