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。
Reported the use of cellulose phosphine - palladium complex as a catalyst, organotin reagents and substituted cinnamoyl chloride cross-coupling synthesis of chalcone compounds. The catalytic performance of the catalyst and the factors affecting the reaction were investigated. XPS experimental results show that the catalytic role of the metal is palladium.
