混合稀土氯化物催化的Diels-Alder反应

本文提出以混合烯土氯化物作为Diels-Alder反应催化剂, 催化三种有工业应用价值的环加成反应。实验结果表明, 混合稀土氯化物对具有含氧基团底物的Diels-Alder反应催化效果显著, 其中混合重烯土氯化物比混合轻稀土氯化物表现出更高的催化活性。。

Diels-alder reactions catalyzed by the mixed rare earth chlorides

The mixed rare earth chlorides were used to catalyze three kinds of Diels-Alder reactions which of industrial significance. They have been found to be very active catalysts for the cycloaddition reactions with reactants having oxygen containing functional groups. The catalytic activity of the mixed heavy rare earth chlorides is higher than that of the mixed light rare earth chlorides.
