  Nickel-Catalyzed Suzuki–Miyaura Reaction of Aryl Fluorides

  摘要：

  Two protocols for the nickel-catalyzed cross-coupling of aryl fluorides with aryl boronic esters have been developed. The first employs metal fluoride cocatalysts, such as ZrF4 and TiF4, which enable Suzuki-Miyaura reactions of aryl fluorides bearing electron-withdrawing (ketones, esters, and CF3), aryl and alkenyl groups as well as those comprising fused aromatic rings, such as fluoronaphthalenes and fluoroquinolines. The second protocol employs aryl fluorides bearing ortho-directing groups, which facilitate the difficult C-F bond activation process via cyclometalation. N-heterocycles, such as pyridines, quinolines, pyrazoles, and oxazolines, can successfully promote cross-coupling with an array of organoboronic esters. A study into the substituent effects with respect to both coupling components has provided fundamental insights into the mechanism of the nickel-catalyzed cross-coupling of aryl fluorides.

  Bu4NOAc can be a multi-purpose medium for a Ru-catalyzed directed o-C–H arylation reaction with functionalized aryl bromides. Acetate plays the role of base and Bu4N salts (excess acetate and side product bromide) behave as ionic liquids. The medium is compatible with both RuCl3·xH2O (major product: di-arylation) and [RuCl2(p-cymene)]2/(p-Tol)3P catalytic systems (major product: mono-arylation).

  Bu 4 NOAc可以是多官能团介质，用于Ru催化的与官能化芳基溴化物进行的定向o -C–H芳基化反应。乙酸盐起碱的作用，Bu 4 N盐（过量的乙酸盐和副产物溴化物）起离子液体的作用。该介质与RuCl 3 · x H 2 O（主要产物：二芳基化）和[RuCl 2（p- cymene）] 2 /（p -Tol）3 P催化系统兼容（主要产物：单芳基化） 。
