Combination of formamide and cyanuric chloride afforded a new combined “CN” source which is highly stable and safe and can be used in organic cyanation transformation reactions instead of common cyanide sources. This study unfolds the efficient Pd‐catalyzedcyanation of aryl halides using TCT‐formamide reagent as a new combined “CN” source.

presented as an efficient, and reusable magnetically heterogeneous catalyst for the C‐O coupling reaction, namely Ullmann condensation reactions in an aqueous medium. This heterogeneous catalyst shows superior reactivity for the C‐O arylation of different aryl halide (chloride, bromide, and iodide) with phenolderivatives to afford the desired products in good to excellent yields within short reaction
The present article describes the synthesis of a new magnetic polyacrylonitrile-based Pd catalyst involving polyacrylonitrile modified via 2-aminopyridine as an efficient support to immobilize Pd nanoparticles. The simple reusability, easy separation and high stability of this Pd complex make it an excellent candidate to generate a C–O bond via Ph-X activation which is a really important subject in

Electron-deficient nitrobenzenes were coupled with phenols/alcohols to form diaryl/alkyl aryl ethers by the aid of NiCl2 as the catalyst. The reactions were conducted under ligand- and oxidant-free conditions without the exclusion of air or moisture. The initial studies upon the mechanism of the reaction revealed two solvent-dependent approaches. In molten TBAB, SNAr mechanism seems to be predominated
