  Jet spectroscopy and excited state dynamics of SiH₂ and SiD₂

  摘要：

  Silylene radicals, SiH2 and SiD2, are generated in a supersonic free jet by ArF laser (193 nm) photolysis of phenylsilane and phenylsilane-α-d3, respectively. LIF excitation and dispersed fluorescence spectra are measured for the ν2 vibronic bands of the Ã 1B1−X̃ 1A1 transition. The heterogeneous predissociation to Si (3P)+H2 is proposed from the anomalous rotational structure in the excitation spectra; the rotational lines of the r(1) subbranch (K′a=0←K■a=1) have stronger intensity than those of the r(0) subbranch (K′a=1←K■a=0), though the latter is expected to be stronger due to the low temperature Boltzmann distribution in the jet. The time-resolved excitation spectra demonstrate shorter lifetime of K′a=1 rovibronic levels in the Ã 1B1 state. The heterogeneous predissociation is interpreted with the second order perturbation: Ã 1B1 –(a-type Coriolis)→X̃ 1A1 -(spin–orbit)→ã 3B1→Si(3P)+H2. It is demonstrated experimentally that there is a potential barrier associated with the dissociation path of ã 3B1→Si(3P)+H2, the height of which is estimated to be 1540–2160 cm−1 from the bottom of the Ã 1B1 state. The electronic transition moment of the Ã 1B1–X̃ 1A1 transition is estimated to be ‖μe‖2=0.26e2a20 from the Einstein equation for spontaneous emission using measured fluorescence lifetimes for single rovibronic levels with Ka=0 and calculated Franck–Condon factors. The onset of a second predissociation channel, Ã 1B1→Si(1D)+H2, at the (0,7,0) vibronic level of SiH2 Ã 1B1 is manifested as a sharp decrease in the observed fluorescence lifetime for the v′2=7, J′=0 level relative to that predicted for a pure radiative lifetime.

  用于多烯醇选择性反应的定向氢原子转移

  摘要：

  描述了氢原子向烯烃的定向转移。该过程由铁络合物催化，并允许多烯醇的位点选择性氢功能化。实验数据表明，羟基与氢化铁中间体的配位在烯丙基醇基序的优先结合中起重要作用，并为自由基氢功能化事件的选择性提供了新的基础。作为概念验证，β-氨基和 γ-氨基醇由相应的多烯醇选择性制备。

  bearing 2,9-diaryl-1,10-phenanthroline ligands exhibit not only unprecedented catalytic activity but also unusual ligand-controlled divergent regioselectivity in hydrosilylation reactions of various alkynes. The hydrosilylation protocol described herein provides a highly efficient method for preparing useful di- and trisubstituted olefins on a relatively large scale under mild conditions, and its use

  disproportionation of phenylsilane leads to diphenylsilane that further reduces the halides. Preliminary mechanistic studies revealed a non-radical pathway and the source of hydrogen is PhSiH3via deuterium labeling studies. Our methodology represents simplicity and provides a good alternative to typical tin, aluminum and boron hydride reagents.

  synthesis of the geometrically less stable Z-enol ethers is challenging. An efficient Z-selective oxidative isomerization process of allyl ethers catalyzed by a cobalt(II) (salen) complex using N-fluoro-2,4,6-trimethylpyridinium trifluoromethanesulfonate (Me3NFPY•OTf) as an oxidant has been developed. Thermodynamically less stable Z-enol ethers were prepared in excellent yields with high geometric control.

  tris(phosphinoamide)-linked heterobimetallic Co/Zr complex (THF)Zr(MesNPiPr2)3CoN2 (1) has been investigated as a catalyst for the hydrosilylation of ketones with PhSiH3. Catalytic activity superior to monometallic Co or Zr analogues has been observed, demonstrating the importance of cooperative reactivity between Co and Zr. Upon examining stoichiometric reactions, complex 1 was found to be unreactive toward PhSiH3

  已经研究了三（膦酰胺）连接的异双金属Co / Zr络合物（THF）Zr（MesNP i Pr 2）3 CoN 2（1）作为酮与PhSiH 3进行硅氢加成反应的催化剂。已观察到优于单金属Co或Zr类似物的催化活性，表明Co和Zr之间协同反应的重要性。通过检查化学计量反应，发现复合物1对PhSiH 3无反应，这表明该机理不同于典型的Chalk–Harrod型氢化硅烷化途径。相反，1易与酮反应，在二苯甲酮的情况下，分离出自由基偶联产物[（Ph 2 CO）Zr（MesNP i Pr 2）3 CoN 2 ] 2（3），这表明与Zr结合的酮基自由基具有中间性分段。提出了一种基于自由基的氢化硅烷化机制，该机制涉及氢原子从PhSiH 3转移到Zr结合的酮基自由基上。
