  Synthesis of arylboronates via Cp*RuCl-catalyzed cycloaddition of alkynylboronates

  摘要：

  In the presence of 5-10 mol% Cp*RuCI(cod), 1,6- and 1,7-diynes were allowed to react with an ethynylboronate at ambient temperature to give rise to bicyclic arylboronates in 64-93% isolated yields. 1,6-Diynes bearing a boronate terminal also underwent cycloaddition with monoalkynes to give the corresponding bicyclic arylboronates.

  acid-derived electrophiles [RFC(O)X] with aryl organometallics (Ar–M′). This reaction was optimized by interrogating the individual steps of the catalytic cycle (oxidative addition, carbonyl de-insertion, transmetalation, and reductive elimination) to identify a compatible pair of coupling partners and an appropriate Pd catalyst. These stoichiometric organometallic studies revealed several critical elements

  本文介绍了脱羰基 Pd 催化的芳基-氟烷基成键反应的发展，该反应将氟烷基羧酸衍生的亲电子试剂 [ RF C (O)X] 与芳基有机金属化合物 (Ar-M') 偶联。通过询问催化循环的各个步骤（氧化加成、羰基脱插入、金属转移和还原消除）来优化该反应，以确定一对相容的偶联伙伴和合适的 Pd 催化剂。这些化学计量有机金属研究揭示了反应设计的几个关键要素。首先，使用 M' = 硼酸酯可以避免R F C(O)X 和 Ar–M'之间未催化的背景反应。二、羰基脱嵌和Ar-R F当 R F = CF 3时，还原消除是催化循环中最慢的两个步骤。更改为 R F = CHF 2后，这两个步骤都会显着加快。计算研究表明，有利的 F 2 C–H---X 相互作用有助于加速该系统中的羰基脱嵌。最后，X = 二氟乙酸盐的金属转移速度较慢，但​​ X = F 的金属转移速度较快。最终，这些研究促成了 (SPhos)Pd
