selective Pd-catalyzed mono-α-arylation of acetone employing aryl chlorides, bromides, iodides, and tosylates. The use of appropriately designed P,N-ligands proved to be the key to controlling the reactivity and selectivity. The reaction affords good yields with substrates containing a range of functional groups at modest Pd loadings using Cs(2)CO(3) as the base and employing acetone as both a reagent and
我们报告了第一个使用芳基氯化物、溴化物、碘化物和甲苯磺酸盐选择性 Pd 催化的丙酮单α-芳基化的例子。使用适当设计的 P,N 配体被证明是控制反应性和选择性的关键。该反应使用 Cs(2)CO(3) 作为碱并使用丙酮作为试剂和溶剂,在适度的 Pd 负载下,使用含有一系列官能团的底物提供良好的产率。
