  [(tBu2PhP)Ag(μ-OCF3)]2：一种热稳定、光不敏感的三氟甲氧基化亲核试剂

  摘要：

  许多三氟甲氧基化方法经常提出亲核 AgOCF 3作为关键中间体。然而，这种中间体的结构仍然难以捉摸。在此，制备了热稳定、光不敏感的亲核三氟甲氧基化试剂[Ag(PPh t Bu 2 )(OCF 3 )] ( 1 )并进行了充分表征。试剂1与多种烷基亲电子试剂反应，包括苄基溴/氯化物、伯烷基溴/碘化物/三氟甲磺酸酯/对硝基苯磺酸酯和仲烷基溴化物/三氟甲磺酸酯/对硝基苯磺酸酯，产率良好至优异。通过与三种对映体富集的二级烷基亲电子试剂反应进行的机理研究表明，这些反应通过 S N 2 途径进行，这与我们最初的机理假设一致。

• Silver-Catalyzed Trifluoromethoxylation of Alkyl Trifluoroborates

  日期：2020.7.2

  A silver-catalyzed trifluoromethoxylation of alkyl trifluoroborates with trifluoromethyl arylsulfonate as the trifluoromethoxylation reagent has been reported for the first time. This reaction is performed under mild reaction conditions and has wide functional group compatibility. In addition, the mechanism of this site-specific trifluoromethoxylation is proposed as a radical pathway.

  Among the general interest in fluorinated compounds, trifluoromethoxylated molecules play a specific role. However, despite this interest, the development of efficient reagents to perform trifluoromethoxylation reactions remains a challenge. Here, 2,4‐dinitro‐trifluoromethoxybenzene (DNTFB) is used as a trifluoromethoxylating reagent to perform nucleophilic substitution under mild metal‐free conditions with different leaving groups, including direct dehydroxytrifluoromethoxylation. A mechanistic study rationalized the reaction and subsequently proposed only three reaction conditions, depending on the reactivity of the starting substrates.

  摘要 在人们对含氟化合物的普遍兴趣中，三氟甲氧基化分子扮演着特殊的角色。然而，尽管人们对三氟甲氧基化反应很感兴趣，但开发高效的试剂仍是一项挑战。本文以 2,4-二硝基三氟甲氧基苯（DNTFB）为三氟甲氧基化试剂，在温和的无金属条件下与不同的离去基团进行亲核取代反应，包括直接脱羟基三氟甲氧基化反应。一项机理研究对该反应进行了合理化，随后根据起始底物的反应活性提出了三种反应条件。
• A deeper insight into direct trifluoromethoxylation with trifluoromethyl triflate

  Commercially available fluorides (silver fluoride and n-tetrabutylammonium triphenyldifluorosilicate), combined with TFMT, allow a simple generation, in situ, of silver and n-tetrabutylammonium trifluoromethoxides which were able to react with electrophilic substrates. Silver trifluoromethoxide, which is usually more efficient than n-tetrabutylammonium trifluoromethoxide, converts, under mild conditions, primary aliphatic bromides and iodides, as well as primary and secondary benzylic or allylic bromides to the corresponding trifluoromethoxylated compounds. Several trifluoromethyl ethers, which could be valuable building-blocks, were prepared in such a way. (C) 2009 Elsevier B.V. All rights reserved.
