Abstract

An efficient method for the synthesis of unsymmetrical diaryl sulfides has been developed by the C–S cross coupling of aryldithiocarbamates and aryldiazonium salts in the presence of CuI-2,2′-bipyridine and Zn. Aryldithiocarbamate compounds have been used here as thiol substitutes. The protocol shows wide substrate scope and good yields of the products.
