An efficient palladium catalytic system for microwave assisted cyanation of aryl halides

CN Bond Formation Using Highly Effective and Reusable Nickel Ferrite Nanoparticles in Water

“…[30,31] These bimetallic compounds that crystallize in the spinel form show superparamagnetic properties originating from the moment of antiparallel spines between ferric ions at tetrahedral sites and nickel ions at octahedral sites. [30,31] In continuation of our previous work, [32][33][34][35][36] we reported the use of a new heterogeneous nickel ferrite nanocatalyst with high efficiency for the CÀN cross-coupling reaction. The presented catalyst system was active and showed good generality in the reaction of various types of aryl halides and different amines or amides such that both aliphatic and aromatic amines and both cyclic and acyclic primary and secondary amines could be coupled with a wide range of aryl halides containing both electron-donating and electron-withdrawing substituents under these reaction conditions.…”

A General, Practical Palladium‐Catalyzed Cyanation of (Hetero)Aryl Chlorides and Bromides

“…[22,23] In contrast, use of P1 afforded 1a in excellent yield (97%) and was operationally simple as the active catalyst is generated efficiently in situ upon exposure to base. Other precatalysts have been applied to Pd-catalyzed cyanations, [24] but this system represents the only example capable of converting aryl chlorides to benzonitriles at low catalyst loading with a non-toxic cyanide source.…”

Fabrication of Pd Nanoparticles Embedded C@Fe3O4 Core–Shell Hybrid Nanospheres: An Efficient Catalyst for Cyanation in Aryl Halides

“…Since then a number of reports were available using this reagent in the presence of Pd catalysts such as Pd(OAc) 2 , 30-31 several Pd complexes [32][33][34][35][36][37][38][39][40][41][42][43][44][45] and Pd/C, [46][47] were developed. The serious drawbacks of these metal catalysts are metal contaminations in the final products, non-reusability and deactivation of the catalysts associated with the use of homogeneous system and hence are still unwelcoming.…”
