Abstract
An unprecedented copper acetate–DMSO
promoted methylthiolation
of arenes and heteroarenes in the presence of air has been developed.
The reaction is highly regioselective under the directing group influence
of pyridine and pyrimidine functional units and gives the thiomethylated
product in moderate to high yields
