• Effective Palladium-Catalyzed Hydroxycarbonylation of Aryl Halides with Substoichiometric Carbon Monoxide
  作者：Signe Korsager、Rolf H. Taaning、Troels Skrydstrup

  DOI：10.1021/ja3114032

  日期：2013.2.27

  A protocol for the Pd-catalyzed hydroxycarbonylation of aryl iodides, bromides, and chlorides has been developed using only 1-5 mol % of CO, corresponding to a p(CO) as low as 0.1 bar. Potassium formate is the only stoichiometric reagent, acting as a mildly basic nucleophile and a reservoir of CO. The substoichiometric CO could be delivered to the reaction from an acyl-Pd(II) precatalyst, which provides

  已开发出一种用于芳基碘化物、溴化物和氯化物的 Pd 催化羟基羰基化的方案，仅使用 1-5 mol% 的 CO，对应于低至 0.1 bar 的 ap(CO)。甲酸钾是唯一的化学计量试剂，作为温和的碱性亲核试剂和 CO 的储库。亚化学计量的 CO 可以从酰基-Pd(II) 预催化剂输送到反应中，提供 CO 和活性催化剂，和从而避免了处理有毒气体的需要。
