  Intramolecular reactivity of arylcarbenes: Biphenyl-2-ylcarbenes

  摘要：

  Biphenyl-2-ylcarbenes, 2-ArC(6)H(4)CR, were generated photolytically and thermally from diazo precursors. Cyclization, leading to fluorenes, competes with capture of the carbenes by methanol but proceeds faster than intramolecular hydrogen shifts (with R = Me) and intermolecular C-H insertion reactions (with R = H in cyclohexane). By comparison of product ratios with kinetic data for related carbenes from the literature, the cyclization rate is estimated as ca 10(11) s(-1). The intramolecular reactivity of biphenyl-2-ylcarbenes is nor significantly attenuated by variation of R (R = H, Me, Ph). Very minor effects of triplet sensitization and methanol quenching indicate that fluorenes arise from spin-equilibrated biphenyl-2-ylcarbenes, presumably from the singlet state. When Ar = mesityl, the carbene predominantly inserts into C-H bonds of the 2'-methyl groups, giving rise to a dihydrophenanthrene. Formation of a fluorene derivative, by formal insertion into C-C bonds, occurs as a minor process. This unprecedented reaction points to intervention of an o-xylylene in which the methyl group migrates. Laser flash photolysis (LFP) of 2-PhC(6)H(4)CN(2)Ph generates a transient absorption which is due to the T-0-->T-n transition of 9-phenylfluorene rather than to the presumed o-xylylene. On LFP of 2-ArC(6)H(4)CN(2)Ph in trifluoroethanol-acetonitrile, protonation of the carbenes gives rise to carbocations, 2-ArC(6)H(4)CH(+)Ph. The transient absorption spectra of these cations are strongly influenced by twisting about the Ar-Ar bond (Ar = Ph < o-tolyl < mesityl) whereas the rates of nucleophilic capture vary only slightly. Biphenyl-2-ylcarbenium ions (Ar = R = Ph) cyclize more slowly than the analogous carbenes, by a factor of greater than or equal to 10(4).

  Nickel catalysts with diazabutadiene ligands promote cross-coupling of benzaldehydes with aryl halides in the presence of zinc as reducing agent, which leads to the corresponding benzhydrols and benzophenones. The benzophenone percentage considerably increases when lithium chloride additive is used.

  catalysts with a PNP type ligand, the electron-rich chiral PNP ligands have still been rarely reported because of the difficulties in synthesis and the nature of air-sensitivity. Herein, we report a novel chiral PNP ligand (Heng-PNP) with both a rigid backbone and a bulky tert-butyl group on the phospholane motif. We successfully obtained its divalent iron complex. The chiral environment of its Ir(III) complex

  尽管通过一系列具有PNP型配体的过渡金属催化剂实现了显着的反应性，但由于合成困难和对空气敏感的性质，富电子手性PNP配体仍然很少报道。在本文中，我们报道了一种新颖的手性PNP配体（Heng-PNP），其磷骨架上具有刚性骨架和庞大的叔丁基。我们成功获得了其二价铁配合物。还通过象限分析讨论了其Ir（III）配合物的手性环境。该三齿配体用于挑战性二芳基酮的铱催化不对称氢化反应：ee最高可达98％达到500吨。计算研究表明，底物中共轭芳基的扭曲（由Ir / Heng-PNP络合物的特殊手性口袋诱导）导致对映体确定步骤中的能量差。
