摘　　要：以氨基酸和1,5-环辛二烯(cod)为配体的铑催化剂催化苯乙炔和2,4-二羟基苯甲醛的氧化偶联反应,并合成了2-苯基-7-羟基-1H-色酮-4-酮.研究了以不同氨基酸为配体的铑催化剂对相同底物的催化效果,结果发现,在相同反应条件下,Rh(cod)(L-Phe)的催化效果最佳.2-Phenyl-7-hydroxy-1H-chromone-4-one was synthesized by the oxidative coupling of phenylacetylene and 2,4-dihydroxy benzaldehyde,using rhodium as the catalyst,amino acid and 1,5-cyclooctadiene(cod)as the ligands.The catalytic effects of rhodium catalysts with different amino acid ligands were compared.The catalytic effect of Rh(cod)(L-Phe)was the best under the same reaction conditions.
