摘要

利用[Ir(ppy)2(dtbbpy)]PF6（ppy = 2-苯基吡啶；dtbbpy = 4,4′-二叔丁基-2,2′-联吡啶）作为光催化剂，开发了一种可见光催化的烯烃与 CO2 的芳基羧化反应，以合成 β-芳基 β,γ-不饱和羧酸。这种多组分方案以原子经济的方式进行，并具有唯一的区域选择性。初步的机理实验表明，烯丙基碳离子是关键的中间产物。

Visible-Light-Catalyzed Regioselective Arylcarboxylation of Allenes with CO2

A visible-light-catalyzed arylcarboxylation of allenes with CO₂ was developed using [Ir(ppy)₂(dtbbpy)]PF₆ (ppy = 2-phenylpyridine; dtbbpy = 4,4′-di-tert-butyl-2,2′-bipyridine) as a photocatalyst to synthesis β-aryl β,γ-unsaturated carboxylic acids. This multicomponent protocol proceeds in an atom-economical way with exclusive regioselectivity. Preliminary mechanistic experiments suggested that allylic carbanion species are the key intermediates.
