Abstract

Pd nanoparticles (NPs) were synthesized by using aqueous extract of leaves of Euphorbia thymifolia L., a non-toxic ecofriendly material. The catalytic activity of the Pd NPs was investigated in the cyanation of aryl iodides using K4Fe(CN)6 as the cyanating agent under ligand-free conditions. The nitriles were obtained in good to excellent yield and the catalyst can be recovered and reused for five times without significant loss of catalytic activity.

摘要

通过使用无毒环保材料——千根癀叶的水提取物合成了钯纳米颗粒(NPs)。在无配体条件下,以K4Fe(CN)6作为氰化剂,研究了钯纳米颗粒在芳基碘化物氰化反应中的催化活性。腈的产率良好至优异,并且该催化剂可以回收并重复使用五次,而催化活性没有明显损失。
