Ï-Allylic azidation of allyl esters was performed with an amphiphilic polystyrene-poly(ethylene glycol) (PS-PEG) resin-supported phosphine-palladium complex in water under heterogeneous conditions to give allyl azides in good to high yields. The polymeric palladium catalyst can be readily recovered and recycled.
在非均相条件下,使用亲水性的聚苯乙烯-聚乙二醇(PS-PEG)树脂支撑的膦-钯络合物,在水相中对烯丙基酯进行烯丙位叠氮化反应,能够以良好至高产率得到烯丙基叠氮化合物。这种聚合物钯催化剂易于回收并可循环使用。
