oxides has been developed, enabling dual C(sp2)–H functionalization along with the cleavage of the C–N bond. The combination between regioselective P-centered radical-triggered [3 + 2] cyclization and C-centered radical-induced cross-coupling in a one-pot manner delivered 27 examples of tribenzo[b,e,g]phosphindole oxides with generally high regioselectivity. A reasonable mechanism for forming such products
已开发出一种新的
DTBP / Mg(NO 3)2介导的邻芳基炔基
苯胺与仲芳基膦氧化物的双环化级联反应,使双C(sp 2)-H官能化以及C-N键的裂解成为可能。区域选择性的P中心自由基触发的[3 + 2]环化与C中心的自由基诱导的交叉耦合的一锅法相结合,提供了27个通常具有较高区域选择性的三苯并[ b,e,g ]
磷吲哚氧化物实例。提出了形成这种涉及自由基加成-环化级联反应的产物的合理机理。
