various spectroscopic techniques. Its catalytic activity was evaluated for the alkoxycarbonylation and aminocarbonylation reactions. These carbonylation reactions were carried out for various substituted aryl bromides using alcohols and amines. Both the reactions were optimized by varying the bases, temperature and solvents. These experiments were carried out under high CO pressure. The catalyst was very
合成了聚合物锚定的
钯(II)催化剂,并使用各种光谱技术对其进行了表征。对于烷氧基羰基化和
氨基羰基化反应,评估其催化活性。这些羰基化反应是使用醇和胺对各种取代的芳基
溴进行的。通过改变碱,温度和溶剂来优化两个反应。这些实验是在高CO压力下进行的。该催化剂非常稳定,可以方便地回收并重复使用六次,而活性和选择性却没有明显下降。
