2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl(Sphos)]-palladacycles containing hydroxymethyl groups 2–3 were prepared by cyclopalladation and chloride bridge-splitting reactions. The complexes were characterized by elemental analysis, ESI–MS and NMR. In addition, single-crystal X-ray analysis reveals that they have one-dimensional lamellar structures involving intermolecular hydrogen bonds and π–π interactions
and/or alkyllithium species reacted smoothly with aryl and/or benzyl ethers with cleavage of the inert C−O bond to afford cross‐coupled products, catalyzed by commercially available [Ni(cod)2] (cod=1,5‐cyclooctadiene) catalysts with N‐heterocyclic carbene (NHC) ligands. Furthermore, the couplingreaction between the aryllithium compounds and aryl ammonium salts proceeded under mild conditions with C−N

4-(hydroxymethyl)phenylboronic acid for the synthesis of substituted biarylmethanols in water. However, substrates are limited to the aryl bromides and activated aryl chlorides. To date, there is no report that investigates the Suzuki reaction of chlorophenylmethanol in water. As a continuation of our interest in the synthesis of biarylmethanols, we have prepared a newphosphine adduct of palladacycle 2 from the
Homo‐ and Heterobimetallic Complexes Bearing NHC Ligands: Applications in α‐Arylation of Amide, Suzuki–Miyaura Coupling Reactions, and Tandem Catalysis
heterobimetallic IrIII/PdII complexfrom a dicarbene donor ligand featuring cyclometalated IrIII and PEPPSI type PdII is presented along with a homodinuclear PEPPSI type PdII complex starting from the same bis‐imidazolium salt. All the PdII complexes are active precatalyst in both α‐arylation and Suzuki–Miyaura coupling reactions. The heterobimetallic IrIII/PdII complex shows much higher yields in
呈现了由具有环金属化的Ir III和PEPPSI类型Pd II的二碳烯供体配体组成的异双金属Ir III / Pd II复合物,以及同同双核PEPPSI类型的Pd II复合物,其起始于相同的双咪唑鎓盐。所有的Pd II络合物在α-芳基化和Suzuki-Miyaura偶联反应中都是活性预催化剂。与它们的单核Pd II和Ir III对应物的等摩尔混合物相比,杂双金属Ir III / Pd II络合物在串联C-C偶联/转移氢化反应中显示出更高的产率。
