Abstract

Copper(II)-catalyzed synthesis of sulfones from sulfinate salts and aryl halides was investigated by means of a combination of experiment and DFT calculation. Experimental results demonstrated the wide applicability of the title approach. The reaction mechanisms are revealed by in-situ IR and theoretical study. It reveals remarkable ligand effect the bidentate amine plays in the reaction, that is, it initially activats the C-I bond of iodobenzene so as to enhance the whole catalytic process.
