Abstract
An efficient synthetic protocol for the Cu-catalyzed cross-coupling of diphenyl diselenide and arylboronic acid at room temperature was described. This catalytic system could tolerate a variety of arylboronic acids with only 3 mol % amount of CuSO4 as the catalyst and inexpensive 1,10-phen. H2O as the ligand. Moreover, this catalytic system used environment-friendly EtOH as the solvent and catalytic amount of Na2CO3 (20 mol %) as the base in the air.
