An ecofriendly and practical method for the efficient synthesis of various sulfonylated N-heteroaromatics in water under metal-free, organic-solvent-free, neutral, and mild reaction conditions was developed. The employment of readily available reagents, wide substrate scope, high chemoselectivity, and regioselectivity make this protocol very practical. Importantly, the pure products can be easily obtained via filtration and washing by alcohol without extraction and recrystallization.
