采用膦氧双齿配体修饰磁性纳米粒子锚定钯（II）复合物[2P-Fe3O4@SiO2-Pd(OAc)2]为催化剂，在无 CO 气体条件下，对芳基碘进行磁性可回收钯-催化甲酰化，以中等到极高的收率得到各种不同的芳醛。该策略中，采用甲酸为 CO 来源和氢供体，采用碘和 PPh3 为活化剂。锚定钯催化剂可通过简单的方法制得，并可采用外部磁场轻松回收，可重复使用 9 次而不会发生任何明显的催化活性损失。

A magnetically recyclable palladium-catalyzed formylation of aryl iodides under CO gas-free conditions has been developed by using a bidentate phosphine ligand-modified magnetic nanoparticles-anchored­ palladium(II) complex [2P-Fe3O4@SiO2-Pd(OAc)2] as catalyst, yielding a wide variety of aromatic aldehydes in moderate to excellent yields. Here, formic acid was employed as both the CO source and the hydrogen donor with iodine and PPh3 as the activators. This immobilized palladium catalyst can be obtained via a simple preparative procedure and can be facilely recovered simply by using an external magnetic field, and reused at least 9 times without any apparent loss of catalytic activity.
