    摘要:

    Exploration of 1,2-phenylenediboronic esters as potential bidentate catalysts for organic synthesis
    摘要:
    Recently, we described the first inverse electron demand Diels-Alder reaction of 1,2-diazene catalyzed by a bidentate Lewis acid. Herein we investigate 1,2-phenylenediboronic esters as potential catalysts for this transformation offering higher stability and easier handling than the currently used boranthracene derivatives. Different 1,2-phenylenediboronic esters were prepared and their ability to form bidentate coordination complexes with phthalazine was analyzed. Although a 1:1 complex was observed, X-ray analysis revealed binding only in a monodentate fashion.

  • Novel Organoborane Lewis Acids via Selective Boron-Tin Exchange Processes Steric Constraints to Electrophilic Initiation by the Boron Halide
    作者:John J. Eisch、Boguslaw W. Kotowicz

    bidentate organoboron Lewis acids, the scope and limitations of synthesizing the requisite organoboranes by the boron-tin exchange between a boron halide and the appropriate organostannane have been examined in detail. The following organotin derivatives have been obtained either from the corresponding RMgBr or RLi reagent and MenSnCl4–n or from a Barbier procedure using the organic halide, Me3SnCl and magnesium
    为了制备新的单齿和双齿有机硼路易斯酸,通过卤化硼和合适的有机锡烷之间的硼-锡交换来合成所需有机硼烷的范围和局限性已被详细研究。以下有机锡衍生物已从相应的 RMgBr 或 RLi 试剂和 MenSnCl4–n 或从使用有机卤化物、Me3SnCl 和镁金属的 Barbier 程序中获得:1,2-双(三甲基锡基)乙炔、o-、m-、和对-双(三甲基-甲锡烷基)苯、α,o-双(三甲基甲锡烷基)甲苯、α,α-双(三甲基锡烷基)-邻二甲苯和2,2-二甲基-2-锡丹。1,2-双(三甲基甲锡烷基)乙炔和异构双(三甲基甲锡烷基)苯与 Et2BBr 的单独相互作用产生相应的双(二乙基硼基)衍生物。相比之下,使用 Et2BCl 时,α,o-双(三甲基甲锡烷基)甲苯仅生成邻二乙基硼基-α-三甲基甲锡基甲苯,而使用 BCl3 时仅生成 α,α'-双(三甲基甲锡烷基)-邻二甲苯,-双-(氯二甲基甲锡烷基)-o-二甲苯。此外,在邻双(三甲基锡基)苯和

    The synthesis and structural properties of organo-bis-dialkylaminochlorboranes X(BNR2Cl)2, X = R2NB(CHCH3)2, o-C6H4, 1-α-C6H4CH2, and 1.8-C10H6 are reported. The steric influence of the alkylamino group and the geometrical situation caused by a chain of sp2 or sp3 hybridized carbon atoms control the formation of intramolecular donor-acceptor bonds. In o-(C6H4)(BNMe2Cl)2 (5) only one amino-boron donor-acceptor

  • Chiral Bimetallic Boronic Esters: A Donor–Acceptor Coexisting Receptor for Amines
    作者:Kyoko Nozaki、Masanori Yoshida、Hidemasa Takaya
    DOI:10.1246/bcsj.69.2043
    日期:1996.7
    A chiral bimetallic Lewis acid, 2,2′-(1,2-phenylene)bis[(4R,5R)-4,5-diphenyl-1,3,2-ioxaborolane] (1a), has been synthesized. The exceptionally strong binding of 1a with benzylamine was demonstrated by titrations. The complex formation ratio of 1a : amine = 1 : 2 was determined by a Job plot. The binding constants, K1 and K2, were determined by non-linear curve fitting to be K1 << K2. The results can be explained in terms of an allosteric effect. The first amine molecule coordinates with one of the two boron atoms of 1a; at the same time, one NH proton interacts with one of the two oxygen atoms in the other dioxaborolane ring to form a hydrogen bond. As a result, the two dioxaborolane rings are conformationally fixed by two-point binding to provide a preferable binding site for the second amine molecule. Although only a small chiral recognition of 1-phenylethylamine has been obtained with 1a, the clear separation of the peaks of the amine provides the possibility to use 1a as an NMR chiral-shift reagent.
