2-(二苯基膦基)乙胺是一种双齿结构的膦配体，磷原子提供两对孤对电子供金属离子配位。可用作反应剂，合成酰胺化合物选择性氢化反应的活性催化剂。它也被用作合成其他膦配体的前体。 应用： 2-(二苯基膦基)乙胺可用作镍催化体系中的双齿配体，用于炔烃经还原[2+2]环加成合成环丁烯的反应。 2-(Diphenylphosphino)ethylamine is a phosphine ligand that has a bidentate structure with the phosphorus atom donating two lone pair electrons to coordinate with metal atoms. It is used as a reactant to synthesize active catalyst for the selective hydrogenation of amides. In addition, it is also used as a precursor to synthesize other phosphine ligands. Application： 2-(Diphenylphosphino)ethylamine can be used as a bidentate ligand in the nickel catalyst system for the reductive [2+2] cycloaddition reaction to synthesize cyclobutenes from alkynes.
