  使用 1-四氢萘酮作为新型二氢源的 TfOH 催化转移氢化反应

  摘要：

  使用 1-四氢萘酮作为新型二氢源，开发了一种前所未有的 TfOH 催化转移氢化反应。各种烯烃以及三苯甲基和二苯甲基衍生物已成功用于该转移氢化反应，从而以良好的收率形成了各种所需产物。氘标记实验表明，1-四氢萘酮的α-氢向烯烃提供质子，导致形成碳正离子，随后捕获源自1-四氢萘酮的β-氢的氢化物，从而促进还原反应。这项研究代表了一项重大进展，因为它证明了酮作为无金属条件下还原反应的新型二氢源的潜力。

• Zn(II)‐Stabilized Azo‐Anion Radical Catalyzed Sustainable C−C Bond Formation: Regioselective Alkylation of Fluorene, Oxindole, and Indoles

  Herein we report a sustainable approach for the alkylation of ketones, 9H‐fluorene, oxindole, and indole using alcohols as the alkylating agent catalyzed by a well‐defined air‐stable zinc catalyst (1 a) of a tridentate redox non‐innocent arylazo ligand, 2‐((4‐chlorophenyl)diazenyl)‐1,10‐phenanthroline (L^a). 2–3 mol % of 1 a efficiently produces substituted α‐alkylated ketones, 9‐alkylated fluorenes, C3‐alkylated oxindoles, and C3‐alkylated indoles in moderate to good isolated yields. In aerial condition, the formation of bis(indolyl)methane (BIMs) derivatives were observed when indoles were subjected to alkylation by primary alcohols. A few drug molecules containing BIMs were prepared in good isolated yields. The catalyst 1 a exhibited good chemoselectivity during the functionalization of fluorene and indole with oleyl alcohol and β‐citronellol. A few control experiments, including deuterium labeling experiments, performed to unveil the reaction mechanism indicate that the one‐electron reduced azo‐anion radical species [1 a]‐formed in situ, acts as the active catalyst. All the redox events occur at the redox‐active aryl‐azo ligand, which acts as the reservoir of hydrogen and electrons throughout the catalytic cycle, keeping the Zn(II)‐center as a template.
