Abstract
Palladium-catalyzed annulation of 1-alkynylphosphine sulfides with 2-iodoanilines followed by desulfidation affords 3-substituted 2-indolylphosphines. This annulation/desulfidation sequential protocol offers a conceptually new approach to bulky heteroarylphosphines.
摘要
钯催化 1-炔基膦硫醚与 2-碘苯胺的环化反应，随后脱硫，得到 3-取代的 2-吲哚基膦。这种环化/脱硫的顺序反应为大位阻杂芳基膦提供了一种全新的概念性方法。
