Heterocycles, 61, 391-401; 2003 这个有制备的 你去找这个文献把 Synthesis and evaluation of novel dirhodium(II) carboxylate catalysts with atropisomeric biaryl backbone. Hikichi, Ken; Kitagaki, Shinji; Anada, Masahiro; Nakamura, Seiichi; Nakajima, Makoto; Shiro, Motoo; Hashimoto, Shunichi. Graduate School of Pharmaceutical Sciences, Hokkaido University, Sapporo, Japan. Heterocycles (2003), 61 391-401. Publisher: Japan Institute of Heterocyclic Chemistry, CODEN: HTCYAM ISSN: 0385-5414. Journal written in English. CAN 140:391351 AN 2004:14726 CAPLUS Abstract Three new dirhodium(II) carboxylate catalysts contg. an axially dissym. biphenyl or binaphthyl skeleton were synthesized and characterized. The x-ray structure of the dirhodium(II) complex incorporating (R)-2'-methoxycarbonyl-6,6'-dimethyl-[1,1'-biphenyl]-2-carboxylate as bridging ligands demonstrates that the four carboxylate ligands are arranged in a C2-symmetry-like conformation. These catalysts provide a reasonable level of asym. induction in intramol. C-H insertion of a-methoxycarbonyl-a-diazoacetamide. Indexing -- Section 29-13 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 75 Ligands Role: RCT (Reactant); SPN (Synthetic preparation); PREP (Preparation); RACT (Reactant or reagent) (bridging; prepn. and reaction of biphenyl- and binaphthylcarboxylate with rhodium acetate to give chiral bridging-biarylcarboxylate dirhodium catalysts for the asym. C-H insertion of diazoacetamides) Crystal structure Molecular structure (of chiral dirhodium tetrakis(biphenyldicarboxylate) Atropisomers (of chiral dirhodium tetrakis(biphenyldicarboxylate) complexes) Asymmetric synthesis and induction Insertion reaction Insertion reaction catalysts (prepn. and reaction of biphenyl- and binaphthylcarboxylate with rhodium acetate to give chiral bridging-biarylcarboxylate dirhodium catalysts for the asym. C-H insertion of diazoacetamides) |
