Meng, Qi; Zhang, Lian; Zhu, Xinhui; Teng, Qiaoqiao published their research in ChemistrySelect in 2021. The article was titled 《Synthesis of 9-O-Arylated Berberine with a Polystyrene Resin Supported Copper(II) Catalyst》.Safety of 4-Iodopyridine The article contains the following contents:
A series of polyfluorobenzene, pyridine and aniline substituted berberine derivatives I (Ar = Ph, 4-H2NC6H4, 3-pyridyl, etc.) were prepared via resin-supported Cu(II) catalyzed cross-coupling reactions of tetrahydroberberrubine with iodoarenes and subsequent I2 oxidation The best catalyst, a polyethyleneimine functionalized polystyrene supported Cu2+ (PSAPA·Cu(II)), could be reused for at least 5 runs without significant loss of catalytic activity. Comparative studies on the morphol. and porous structures of the materials suggested a catalyst with a moderate sp. surface area and larger pore diameters was more active in catalyzing the cross-coupling reactions.4-Iodopyridine(cas: 15854-87-2Safety of 4-Iodopyridine) was used in this study.
4-Iodopyridine(cas: 15854-87-2) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.Safety of 4-Iodopyridine
