Sodium (4-chlorophenyl)methanesulfinate is an alkyl Baran Diversinate. These reagents facilitate the functionalization of heteroaromatic C-H bonds under simple reaction conditions.The following Baran Sulfinate is a part of a toolbox of diversification reagents, which are ideal for the late-stage functionalization of nitrogen-containing heterocycles. The regioselectivity can be effectively tuned by modification of the pH and solvent selection.
