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.
钯催化的1-炔基膦硫化物与2-碘苯胺的环化,然后进行脱硫,得到3-取代的2-吲哚基膦。这种环化/脱硫顺序方案为大体积的杂芳基膦提供了一种概念上新的方法。
