含有L-氨基酸为配体的铑催化剂合成与研究

Synthesis and Study of Rhodium Catalyst Containing L-amino Acid as Ligand

金属铑作为催化剂被发现的相对较晚,但其发展的速度快,化工生产是铑催化剂最常用的地方。铑受大家欢迎是因为它具有高活性,反应过程中不需要高难的条件,而且具有较高的选择性。本文将RhCl_(3)与1,5环辛二烯反应,合成二氯(1,5-环辛二烯)合铑,阐述了含有L-氨基酸为配体的铑催化剂的制备条件,以核磁共振氢谱(1N-NMR)、红外光谱(IR)电镜扫描为依据,证明了产物的化学结构,并通过对照试验得出了反应的最佳条件。

Rhodium was found relatively late as a catalyst,but its development speed is fast.Chemical production is the most commonly used place of rhodium catalyst.Rhodium is popular because of its high activity,high selectivity and no need of difficult conditions.In this paper,RhCl_(3) was reacted with 1,5-cyclooctadiene to synthesize dichloro(1,5-cyclooctadiene)rhodium.The preparation conditions of rhodium catalyst with L-amino acid as ligand were described.The chemical structure of the product was proved by 1H-NMR and IR scanning electron microscope.The optimum reaction conditions were obtained by contrast experiment.
