    Palladium-catalyzed biaryl-coupling reaction of arylboronic acids in water using hydrophilic phosphine ligands
    摘要:
    Hydrophilic phosphine ligands possessing a carbohydrate side-chain, such as N-(4-diphenylphosphinophenyl)methyl gluconamide (9), N-[4-(2'-dicyclohexylphosphinobiphenyl)phenylmethyl] gluconamide (10), and N-[4-(2'-di-t-butylphosphinobiphenyl)]phenylmethyl gluconamide (11), were newly synthesized to carry out palladium-catalyzed biaryl coupling of arylboronic acids in a single aqueous medium. The catalyst prepared in situ from Pd(OAc)(2) and 10 exhibited a higher efficiency than that of 9, 11, Ph2P(m-C6H4SO3Na) (TPPMS) or P(m-C6H4SO3Na)(3) (TPPTS) for representative aryl bromides, chlorides, or triflates. The catalyst prepared in situ from Pd(OAc)(2) (0.001 mol%) and 10 (0.002 mol%) achieved 96,000 TON in the reaction of p-tolylboronic acid with 4-bromoacetophenone in water.

  • The Methoxycarbonylation of Vinyl Acetate Catalyzed by Palladium Complexes of [1,2-Phenylenebis(methylene)]bis[di(tert-butyl)phosphine]
    作者:Adam J. Rucklidge、George E. Morris、Alexandra M. Z. Slawin、David J. Cole-Hamilton

    Palladium complexes of [1,2-phenylenebis(methylene)]bis[di(tert-butyl)phosphine] (1) catalyze the methoxycarbonylation of vinyl acetate (= ethenyl acetate) in the presence of methanesulfonic acid (Scheme 1). High selectivities to ester products can be obtained if free phosphine ligand is in excess over the amount of added acid (Table 1). Selectivities to methyl 2-acetoxypropanoate, a precursor to lactate

    作者:Enrique Huang Kwan、Yasushi Jack Kawai、Sei Kamakura、Makoto Yamashita

    日期:——
    long-tethered boron-containing (P–B–P)-pincer ligand 8 has been synthesized. Complexation of 8 with [Ir(coe)2Cl]2 (coe = cyclooctene) resulted in (P–B–P)(hydrido)chloroiridium complex (P–B–P)Ir(H)Cl 9. Subsequent reaction with nBuLi led to the formation of dihydride complex (P–B–P)Ir(H)210. Both complexes were found to be moderately active for the catalytic dehydrogenation of alkanes.

  • Proline-Based P,O Ligand/Iridium Complexes as Highly Selective Catalysts: Asymmetric Hydrogenation of Trisubstituted Alkenes
    作者:Denise Rageot、David H. Woodmansee、Benoît Pugin、Andreas Pfaltz
    DOI:10.1002/anie.201104105
    日期:2011.10.4
    O joins the mix: P,O ligands (L1) form efficient iridium catalysts for the asymmetric hydrogenation of olefins. The proline‐derived ligands lead to high enantioselectivities with several classes of alkenes, most notably with α,βunsaturated carboxylic esters and ketones, where they match or even surpass the ee values reported for the best N,P and C,N ligands.
    P,O加入混合物:P,O配体(L1)形成有效的铱催化剂,用于烯烃的不对称加氢。脯氨酸衍生的配体对几种烯烃具有很高的对映选择性,最显着的是与α,β-不饱和羧酸酯和酮匹配,甚至超过了 报道的最佳N,P和C,N配体的ee值。

For both ligands, the dimethylamides [A]M(NMe2)3 ([A]1-M) and [B]M(NMe2)3 ([B]1-M) were prepared and converted to the iodides [A]MI3 ([A]2-M) and [B]MI3 ([B]2-M) (M = Zr, Hf). Starting from these iodides, the corresponding benzyl derivatives [A]MBn3 ([A]3-M) and [B]MBn3 ([B]3-M) (M = Zr, Hf) were obtained via reaction with Bn2Mg(OEt2)2. For zirconium, the benzylic
