• Solvent selective phenyl selenylation and phenyl tellurylation of aryl boronic acids catalyzed by Cu(II) grafted functionalized polystyrene

  A solvent-selective methodology for the phenyl selenylation and phenyl tellurylation of aryl boronic acids has been developed for the first time using a polymer supported Cu(II) catalyst. The catalyst was synthesized by anchoring Cu(OAc)(2) onto a functionalized polystyrene with pyridine thiosemicarbazone ligand. It was then characterized properly by SEM, EDAX, FT-IR, TGA, and EPR experiments. The catalyst smoothly catalyzes phenyl selenylation of aryl boronic acids in water and phenyl tellurylation of aryl boronic acids in PEG-600, selectively. Thus a wide variety of unsymmetrical organodiaryl or aryl-heteroaryl selenides and tellurides have been synthesized by this protocol. The catalyst was recycled up to six runs without any appreciable loss of catalytic activity. (C) 2014 Elsevier Ltd. All rights reserved.
• A convenient and efficient copper-catalyzed synthesis of unsymmetrical and symmetrical diaryl chalcogenides from arylboronic acids in ethanol at room temperature

  A simple and convenient approach for the synthesis of unsymmetrical diaryl chalcogenides (Te, Se, and S) has been developed by copper-catalyzed cross-coupling reaction of organoboronic acid with diaryl dichalcogenide in ethanol using NaBH4 in air or oxygen. The present methodology is highly practical for the synthesis of unsymmetrical diaryl tellurides with various functionalities such as -NO2, -F, -Br, and -COOH that have been obtained in good to excellent yields. Methodology is also effective for the synthesis of unsymmetrical diaryl selenides and sulfides. Moreover, symmetrical diaryl selenides have also been obtained from arylboronic acids using elemental selenium powder under optimized reaction conditions. The use of NaBH4 is the key for the development of milder reaction conditions, which enable the construction of unsymmetrical diaryl chalcogenides from boronic acid substrates in ethanol at room temperature.
