  三烯丙基（芳基）硅烷与芳基溴化物和氯化物的交叉偶联：一种替代的便捷联芳基合成

  摘要：

  在DMSO-H 2 O中存在PdCl 2 / PCy 3和氟化四丁基铵（TBAF）的情况下，多种芳基溴化物与三烯丙基（芳基）硅烷的交叉偶联是有效的，以高收率得到各种联芳基。值得一提的是，全碳取代的芳基硅烷对水分，酸和碱稳定，易于获得，可作为其芳基（卤代）硅烷对应物的高度实用替代品。由[（η的催化剂体系3 -C 3 H ^ 5）的PdCl] 2和2- [2,4,6-（我-Pr）3 c ^ 6 ħ 2 ] -C 6 H ^ 4 PCY2和在THF-H 2 O中使用TBAF·3 H 2 O对于与芳基氯的交叉偶联特别有效。两种催化剂体系均能耐受多种常见的官能团。推测反应的高效率归因于用TBAF·3 H 2 O和适量的水处理后烯丙基的易裂解。二烯丙基（二苯基）硅烷还可以与各种芳基溴化物和氯化物交联，收率很高，而烯丙基（三苯基）硅烷只能以中等收率得到交联产物。通过溴氯苯与不同芳基硅烷的顺序交叉偶联，可

• Preparation of Indolenines via Nucleophilic Aromatic Substitution
  作者：Florian Huber、Joel Roesslein、Karl Gademann

  DOI：10.1021/acs.orglett.9b00489

  日期：2019.4.19

  An unusual aromatic substitution to access indolenines is described. 2-(2-Methoxyphenyl)acetonitrile derivatives are reacted with various alkyl and aryl Li reagents to furnish the corresponding indolenine products, constituents of natural products, and cyanine dyes such as indocyanine green. This new method was used to synthesize 41 indolenines with large functional group tolerance, and selected examples

  Catalytic hydrodefluorinations of organofluorine compounds by low-valent niobium catalyst were developed. In the presence of niobium(V) chloride (typically, 5 mol%), fluorobenzenes, α,α,α-trifluorotoluenes and (trifluoromethyl)pyridines were hydrodefluorinated with lithium aluminum hydride to give the corresponding benzenes, toluenes and methylpyridines in good yields, respectively.
