摘要
报道了采用纤维素氧膦 -钯络合物为催化剂 ,有机锡试剂与取代肉桂酰氯进行交叉偶联合成查耳酮化合物。考察了催化剂的催化性能及影响反应的因素。 XPS实验结果表明 ,催化剂中起催化作用的是金属态钯。
This paper presents the cross\|coupling reaction of organotins with substituted cinnamoyl chlorides catalyzed by cellulose oxyphosphine palladium complex for the synthesis of chalcones.The reaction conditions and catalyzed mechanism were also disscused.The catalyst has been investigated by XPS and the experimental results show that the metallic Pd may be the active center for the coupling reacition.
