    Cyclization/Hydrosilylation of Functionalized Dienes Catalyzed by a Cationic Palladium Phenanthroline Complex
    摘要:
    Mixtures of(phen)PdMe2 (2a) and HBAr'(4) (3a) or (phen)PdMe(Cl) (2b) and NaBAr'(4) (3b) [phen = 1, 10-phenanthroline; Ar' = 3,5-C6H3(CF3)(2)] catalyzed the cyclization/hydrosilylation of functionalized 1,6-dienes to form silylated cyclopentanes in good yield and with excellent trans selectivity about the newly formed C-C bond (typically >50:1). A range of tertiary hydrosilanes were employed in the procedure although unhindered trialkylsilanes provided the most consistent results. The protocol tolerated a range of polar functionality including esters, ethers, amides, sulfones, and cyano groups. 4,4-Disubstitution on the diene backbone promoted cyclization, and a homoallylic ester, ketone, or ether directing group was required for efficient cyclization. The procedure tolerated dienes which possessed a single trans-substituted olefin and also tolerated allylic substitution. These substituted dienes underwent cyclization/hydrosilylation to form carbocycles resulting from transfer of the silyl group to the less hindered olefin. Mixtures of 2a and 3a also catalyzed the cyclization/hydrosilylation of functionalized 1,7-dienes to form silylated cyclohexane derivatives. Cyclization/hydrosilylation of 1,7-dienes was typically slower, less stereoselective, and more sensitive to substitution than was cyclization of 1,6-dienes.

    especially where the competing hydrogen evolution reaction (HER) is thermodynamically and kinetically competent. In this study, we investigate how the selectivity of a tris(phosphine)borane iron(I) catalyst, P3BFe+, for catalyzing the nitrogen reduction reaction (N2RR, N2-to-NH3 conversion) versus HER changes as a function of acid p Ka. We find that there is a strong correlation between p Ka and N2RR efficiency
    N2、CO2 和 O2 等小分子还原多电子/质子催化中的底物选择性是催化剂设计的主要挑战,特别是在竞争性析氢反应 (HER) 具有热力学和动力学能力的情况下。在本研究中,我们研究了三(膦)硼烷铁(I)催化剂 P3BFe+ 催化氮还原反应(N2RR、N2-to-NH3 转化)与 HER 的选择性如何随酸 p Ka 的变化而变化。我们发现 p Ka 和 N2RR 效率之间存在很强的相关性。化学计量研究表明,所用的苯胺三氟甲磺酸盐仅在茂金属还原剂Cp*2Co存在的情况下与N2还原的早期中间体(例如Fe(NNH)或Fe(NNH2))的形成相容。这表明酸和还原剂的相互作用在 NH 键形成反应中发挥着关键作用。DFT 研究确定质子化茂金属物质是强 PCET 供体,并表明它应该能够形成对 N2RR 至关重要的早期 NH 键。此外,DFT 研究还表明,观察到的 p Ka 对 N2RR 效率的影响可归因于不同苯胺酸的

    The prototypical iron(0) complex [Fe(CO)3(PMe3)2] (1) forms a frustrated Lewis pair (FLP) with B(C6F5)3 (BCF). In this FLP, the iron complex acts as the Lewis base partner, and the borane as the Lewis acid partner. This FLP is able to cleave H–H, H–Cl, H–O and H–S bonds in H2, HCl, H2O and HSPh. The FLP 1/BCF is shown to catalyze the hydrogenation of alkenes under mild conditions, where terminal alkenes

    Abstract

    A monocationic Zn(II) acetate complex of a C2-chiral bisamidine-type sp2N bidentate ligand (LR) possessing two dioxolane oxygen n orbitals in the reaction site catalyzes, without the use of an external base, a highly efficient asymmetric 1,3-dipolar cycloaddition (1,3-DC) of tridentate α-substituted α-imino esters with acrylates, attaining up to &gt;99:1 enantiomeric ratio with perfect regio- and diastereo-selectivities. A catalyst loading of 0.1 mol% is generally acceptable to furnish various chiral multi-substituted prolines. Both (S)-α-imino ester and the R enantiomer show a high level of enantioselectivity. An overall picture of the present 1,3-DC has been revealed via analyses of substrate structure/reactivity/selectivity relationships, NMR, MS, X-ray diffraction, 12C/13C isotope effects, rate law, and kinetics. The first success in the high performance 1,3-DC is ascribed to i) a Brønsted base/Lewis acid synergistic effect of [Zn(OAc)LR]OTf (R cat); ii) the existence of the n orbital, which determines the position of the intermediary N,O-cis-Zn enolate (dipole) by an n-π* non-bonding attractive interaction between the oxygen atom in LR and the C=N moiety of the dipole; and iii) utilization of chelatable α-imino esters capturing Zn(II) as a tridentate ligand. A 12C/13C analysis has clarified that a stepwise 1,3-DC mechanism is operating.
