A metal-free one-pot two-step synthesis of sulfonamides from readily available nitroarenes and sodium arylsulfinates in a mixture of methanol and water has been developed. In this procedure, the aryl amines were produced in situ by the reduction of nitroarenes mediated by diboronic acid, and then coupled with sodium arylsulfinates in the presence of iodine. A series of N-arylsulfonamides with various functional groups were obtained in moderate to good yields under the optimal reaction conditions. In addition, this one-pot process is applicable for gram-scale synthesis.

A copper-catalyzed Chan-Lam-coupling-like reaction of a (het)arylboronic acid and chloramine-T (or a related compound) has been developed for the synthesis of N -arylsulfonamides at room temperature in moderate to good yields, with good tolerance of functional groups. In this process, it is believed that chloramine-T serves as an electrophile.

A green and practical method for the synthesis of N-arylsulfonamides from chloramine salts and arylboronic acids is herein developed. The reaction proceeds readily in the presence of 5 mol% of CuI and 2.5 equiv. K2CO3 in water at room temperature, generating a variety of N-arylsulfonamides in moderate to good yields with good functional group tolerance.
