Abstract
An efficient Cu(I)-catalysed synthesis of diaryl sulfones from arylsulfinic acid salts and aryl bromides in 1,3-dimethyl-2-imidazolidinone at 80 °C in the presence of CuBr and pyridine has been developed. The high-yielding process exhibits significant functional group tolerance and allows for the preparation of a number of diaryl sulfones under mild conditions.
