Extending the NHC Concept: C-C Coupling Catalysis by a PdII Carbene (rNHC) Complex with Remote Heteroatoms

A palladium complex, trans‐Cl(PPh3)2Pd{Ca‐cyclo‐C6H4‐o‐N(Me)C=CbH}(Ca—Cb), that contains a carbene ligand with remote heteroatoms (rNHC) is much more active in certain C–C coupling reactions than comparably simple NHC‐ and phosphane‐containing precatalysts. The rNHC ligand binds strongly by electros...

Summary:A palladium complex, trans‐Cl(PPh3)2Pd{Ca‐cyclo‐C6H4‐o‐N(Me)C=CbH}(Ca—Cb), that contains a carbene ligand with remote heteroatoms (rNHC) is much more active in certain C–C coupling reactions than comparably simple NHC‐ and phosphane‐containing precatalysts. The rNHC ligand binds strongly by electrostatic as well as orbital interaction to the metal. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
