A Novel and sensitive spot-test for m-dinitroaromatics and their derivatives with sodium sulphite and dimethylsulphoxide

Sodium sulphite has been used for a very sensitive characterization of m-dinitroaromatics and their derivatives, with dimethylsulphoxide as solvent.     

Copper-catalyzed cross-coupling of chloramine salts and arylboronic acids in water: A green and practical route to N-arylsulfonamides

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.
