Palladium nanoparticles supported on magnetic copper ferrite nanoparticles: The synergistic effect of palladium and copper for cyanation of aryl halides with K4[Fe(CN)6]

Synthesis of new cyano‐substituted analogues of Tröger's bases from bromo‐derivatives. A stereochemical dependence of long‐range (nJHH, n = 4, 5, and 6) proton–proton and proton–carbon (nJCH, n = 1, 2, 3, 4, and 5) coupling constants of these compounds

“…For cyanation of aryl halides, the Rosenmund‐von Braun reaction mediated by copper (I) cyanide has been widely used . Recent methodologies have been developed for this reaction using palladium as catalyst, and different sources of nitriles as malononitrile, potassium hexacyanoferrate (II), and ammonium bicarbonate …”

Application of biosynthesized palladium nanoparticles (Pd NPs) on Rosa caninafruit extract‐modified graphene oxide as heterogeneous nanocatalyst for cyanation of aryl halides

“…A likely mechanism for the Pd NPs/RGO‐ Rosa canina ‐catalyzed cyanation reaction is a well‐known mechanism relating to cyanation of aryl halides, which occurs on the catalyst surface (Scheme ) . The reaction progressed by the oxidative addition of aryl halide over catalyst and continued via moving cyanide anion from K 4 [Fe (CN)] 6 , and finally the reductive removal phase resulted in the aryl cyanide product.…”

2-(diphenylphosphino)pyridine platinum (I) and palladium (I) complex as an efficient binuclear catalyst for Suzuki-Miyaura coupling reaction in water under mild reaction conditions

“…Also, bimetallic Au/ Pd alloy nanoclusters showed excellent reactivity for Ullmann coupling of chloroarenes in aqueous media at low temperature [28,29]. Recently, we have demonstrated synergistic effect between palladium and copper species using copper ferrite supported palladium nanoparticles in cyanation reaction of aryl halides [30]. Most recently, we have also reported assemblies of copper ferrite and palladium nanoparticles on silica spheres as a bimetallic catalyst for Sonogashira coupling reaction [31].…”
