alkenes with aryl iodides under air in MeCN. The reaction of tertiary propargylic alcohols (1) with aryl iodides (2) yields, stereoselectively, γ,γ-diarylallylic alcohols (3) in moderate to high yields and high selectivity. Also, the HT/Pd hydroarylation reaction with aryl iodides was attempted on norbornene and α,β-unsaturated ketones affording, respectively, exo-aryl bicyclo[2.2.1]heptanes and β-aryl ketones
负载在Mg / Ca水滑石上的钯纳米粒子在MeCN中在空气中催化不同炔烃和烯烃与芳基碘化物的加氢芳基化反应。叔炔丙醇(1)与芳基碘化物(2)的反应以中等至高产率和高选择性立体选择性地产生γ,γ-二芳基烯丙醇(3)。此外,尝试在降冰片烯和α,β-不饱和酮上与芳基碘进行HT / Pd加氢芳基化反应,分别提供中等至高收率的外芳基双环[2.2.1]庚烷和β-芳基酮。所描述的所有反应都受益于使用非均相催化剂,该非均相催化剂在反应纯化和催化剂的可循环性方面具有明显的优势。
