You, Shengyong; Zhang, Rongli; Cai, Mingzhong published their research in Synthesis in 2021. The article was titled 《A Magnetically Recyclable Palladium-Catalyzed Formylation of Aryl Iodides with Formic Acid as CO Source: A Practical Access to Aromatic Aldehydes》.Application In Synthesis of 3-Iodophenol The article contains the following contents:
A magnetically recyclable palladium-catalyzed formylation of aryl iodides ArI (Ar = C6H5, 3-pyridyl, 2-furyl, etc.) 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 ArCHO 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 facilely recovered simply by using an external magnetic field, and reused at least 9 times without any apparent loss of catalytic activity. In the experimental materials used by the author, we found 3-Iodophenol(cas: 626-02-8Application In Synthesis of 3-Iodophenol)
3-Iodophenol(cas: 626-02-8) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Application In Synthesis of 3-Iodophenol Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.
