  A C–H Borylation Approach to Suzuki–Miyaura Coupling of Typically Unstable 2–Heteroaryl and Polyfluorophenyl Boronates

  摘要：

  A method for the synthesis of biaryls and heterobiaryls from arenes and haloarenes without the intermediacy of unstable boronic acids is described. Pinacol boronate esters that are analogous to unstable boronic acids are formed in high yield by iridium-catalyzed C-H borylation of heteroarenes and fluoroarenes. These boronates are stable in the solid state or in solution and can be generated and used in situ. They couple with aryl halides in the presence of simple palladium catalysts, providing a convenient route to biaryl and heteroaryl products that have been challenging to prepare via boronic acids.

  This article describes the design, optimisation and development of a Suzuki cross-coupling protocol mediated by an efficient palladium-encapsulated catalyst (Pd EnCat) under microwave irradiation. The methodology has been used in both batch mode for classical library preparation and in continuous-flow applications furnishing multigram quantities of material. Described is a method that uses direct focused

  本文介绍了在微波辐射下由高效钯封装的催化剂（Pd EnCat）介导的Suzuki交叉偶联方案的设计，优化和开发。该方法已在批处理模式下用于经典文库制备，并已在连续流应用中使用，以提供数克的材料。描述了一种在施加外部冷却源的同时使用直接聚焦微波加热的方法。这使得可以在整个反应期间保持低于正常的总体温度，从而导致反应产物的总产率和纯度的显着提高。关于固定催化剂体系的延长寿命和增强的反应性，讨论了该新颖的加热方案的其他方面。

  arenediazonium chlorides in the presence of cupric chloride as catalyst gives 2-acetyl-5-arylthiophenes. These products react with 5-chloro- and 5-bromoisatins to give 6-chloro- and 6-bromo-substituted 2-(5-aryl-2-thienyl)-4-quinolinecarboxylic acids.

  A novel copper‐catalyzed CH arylation of heteroarenes with anilines by an in situ diazonium reaction is established by using silver nitrite (AgONO) as an unconventional nitrosating reagent under acid‐free conditions. It provides a complementary approach for the CH arylation of electron‐rich heteroarenes with aromatic amines affording a variety of heterobiaryls in moderate to good yields.
