A general and efficient procedure has been developed for the synthesis of organochalcogenides (selenides and tellurides) by a simple reaction of organoboronic acids and dichalcogenides catalysed by CuFe2O 4 nanoparticles in PEG-400 without any ligand. This protocol offers the scope for access to a wide spectrum of chalcogenides including diaryl, aryl-heteroaryl, aryl-styrenyl, aryl-alkenyl, aryl-allyl, aryl-alkyl and aryl-alkynyl versions. The catalyst is magnetically separable and recyclable eight times without any loss of appreciable catalytic activity. The products are obtained in high purities after evaporation of solvent followed by filtration column chromatography. The Royal Society of Chemistry.

A convenient, general and efficient procedure for the synthesis of unsymmetrical diaryl chalcogenides has been developed by the reaction of aryl diazonium fluoroborates and diaryl dichalcogenides in the presence of zinc dust in dimethyl carbonate under microwave irradiation. The reactions of a wide range of substituted aryl diazonium fluoroborates and diaryl dichalcogenides have been addressed. The zinc dust is required for the cleavage of diaryl dichalcogenides. The products are obtained in high purity after fast column chromatography of the crude residue after evaporation of dimethyl carbonate. The Royal Society of Chemistry 2012.

Tolyl arylazo sulfones react with various alkyl- and arylseleno reagents to produce substituted alkyl aryl and unsymmetrical diaryl selenides.The corresponding tellurides can also be obtained.Isolated yields in both cases are good.This procedure is an interesting alternative to the classical Sandmeyer reaction.
DIARYL TELLURIDES FROM THE REACTION OF MODERATELY ACTIVATED IODOARENES WITH BENZENETELLUROLATE ION IN HEXAMETHYLPHOSPHORIC TRIAMIDE
Suzuki, Hitomi,Abe, Hisako,Ohmasa, Nobuko,Osuka, Atsuhiro
, p. 1115 - 1116 (2007/10/02)
When heated in hexamethylphosphoric triamide at 80-90 deg C, preferably in the presence of copper(II) iodide, moderately activated iodoarenes undergo nucleophilic attack by benzenetellurolate ion , giving the corresponding unsymmetrical diaryl tellurides
