A simple procedure for the palladium-catalyzed cyanation of aryl halides is described via a nucleophilic non-toxic cyanide source, K₄[Fe(CN)₆] in the presence of Pd/coral reef nanocomposite as a heterogeneous catalyst; the protocol provides a useful and easy method for the synthesis of aryl nitriles that are generated from the corresponding variant aryl halides, with sodium carbonate as a base. The nanocatalyst was prepared by a biological process using aqueous extract of leaves of as a stabilizing and reducing agent and coral reef as a natural support, without deploying any hazardous chemicals. The catalyst, that is easily separable from the reaction mixture and reused multiple times, was characterized by FT-IR (Fourier-Transform Infrared Spectroscopy), ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy), XRD (X-ray Diffraction), TEM (Transmission Electron Microscopy), FE-SEM (Field Emission Scanning Electron Microscopy), EDS (Energy Dispersive X-ray Spectroscopy) and elemental mapping.
描述了一种通过亲核无毒氰化物源K₄[Fe(CN)₆]在Pd/珊瑚礁纳米复合材料作为多相催化剂存在下对芳基卤化物进行钯催化氰化的简单方法；该方案提供了一种有用且简便的方法，用于由相应的各种芳基卤化物合成芳腈，以碳酸钠作为碱。该纳米催化剂通过生物过程制备，使用[植物名称]叶片的水提取物作为稳定剂和还原剂，以珊瑚礁作为天然载体，无需使用任何危险化学品。该催化剂易于从反应混合物中分离并可多次重复使用，通过傅里叶变换红外光谱（FT-IR）、电感耦合等离子体原子发射光谱（ICP-AES）、X射线衍射（XRD）、透射电子显微镜（TEM）、场发射扫描电子显微镜（FE-SEM）、能量色散X射线光谱（EDS）和元素映射进行了表征。 （注：原文中“using aqueous extract of leaves of as a stabilizing and reducing agent”这里“of leaves of ”后面缺少具体植物名称）
