  A Suzuki Coupling Based Route to 2,2‘-Bis(2-indenyl)biphenyl Derivatives

  摘要：

  Because of the promising performance in olefin polymerization of 2,2'-bis(2-indenyldiyl)biphenyl zirconium dichloride, we developed a new and broadly applicable route to 2,2'-bis(2-indenyl)biphenyl derivatives. Reaction of the known 2,2'-diiodobiphenyl (26) with the new 2-indenyl boronic acid (23) did not result in the desired 2,2'-bis(2-indenyl)biphenyl (10); instead an isomer thereof, (spiro-1,1-(2,2'-biphenyl)-2-(2-indenyl)indane) (27), was obtained. It was found that compound 10 could be made via a palladium-catalyzed reaction of 2,2-biphenyldiboronic acid (31) with 2-bromoindene (21) under standard Suzuki reaction conditions. However, the yield of this reaction was low at low palladium catalyst loadings, due to a competitive hydrolysis reaction of 2,2-biphenyldiboronic acid (31). HTE techniques were used to find an economically viable protocol. Thus, use of the commercially available 1.0 molar solution of (n-BU)(4)NOH in methanol with cosolvent toluene led to precipitation of the pure product in a fast and clean reaction, using only 0.7 mol % (0.35 mol % per C-C) of the expensive palladium catalyst.

• Use of “Homeopathic” Ligand-Free Palladium as Catalyst for Aryl-Aryl Coupling Reactions
  作者：Asaf Alimardanov、Lizette Schmieder-van de Vondervoort、André H. M. de Vries、Johannes G. de Vries

  DOI：10.1002/adsc.200404210

  日期：2004.12

  We have previously shown that the use of ligand-free palladium employing Pd(OAc)2 as catalyst precursor in the Heck reaction of aryl bromides is possible if low catalyst loadings, typically between 0.01–0.1 mol % are used. We have now tested this phenomenon, which we have dubbed “homeopathic” palladium, in biaryl formation using the Suzuki, the Negishi and the Kumada cross-coupling reactions. The Suzuki

  先前我们已经表明，如果使用低催化剂负载量（通常在0.01-0.1 mol％之间），则可以在芳基溴的Heck反应中使用以Pd（OAc）2为催化剂前体的无配体钯。现在，我们使用铃木，根岸和熊田交叉偶联反应在联芳基形成中测试了这种被称为“顺势疗法”钯的现象。使用0.02–0.05 mol％的Pd（OAc）2可以进行活化和失活的芳基溴化物的Suzuki反应。在该反应中，活化的底物的转换频率高达30,000。如果存在强吸电子取代基，甚至芳基氯化物也可能发生反应。Negishi与各种芳基卤化锌的偶联可能在含有吸电子取代基的芳基溴化物上进行。熊田反应仅在“顺势疗法”条件下产生低产率的产物。

  A silylation of vinyliodonium salts using zinc-based silicon reagents as nucleophiles is reported. This cross-coupling is catalyzed by copper, and vinylsilanes are obtained in high yield likely following a Cu(I)/Cu(III) reaction mechanism. The procedure is operationally simple, neither air- nor moisture-sensitive, and tolerant of a range of functional groups. The new method is an addition to the still
