This work reports the green synthesis of the Cu/reduced graphene oxide/FeO (Cu/RGO/FeO) nanocomposite as a new catalytic system for cyanation of aldehydes to nitriles. This nanocomposite catalytic system was synthesized by aqueous extract of leaves of Euphorbia bungei Boiss as a reducing and stabilizing agent. Various substituted aryl nitrile were prepared under optimized conditions and providing moderate to excellent yields. In this process the catalyst exhibited a strong magnet response and could be easily separated by an external magnet and reused with no loss of catalytic activity.
本研究报道了通过绿色合成法制备铜/还原氧化石墨烯/氧化亚铁（Cu/RGO/FeO）纳米复合材料，作为一种将醛转化为腈的新型催化体系。该纳米复合催化体系以大戟叶的水提取物作为还原剂和稳定剂合成。在优化条件下制备了各种取代芳基腈，产率适中至优异。在此过程中，催化剂表现出强烈的磁响应，可通过外部磁铁轻松分离，并可重复使用而不损失催化活性。
