An　efficient　protocol　for　the　synthesis　of　sulfonamides　via　the　electrochemical　oxidative　amination　of　sodium　sulfinates　has　been　developed.　The　chemistry　proceeds　in　a　simple　undivided　cell　employing　a　substoichiometric　amount　of　NH4I　that　serves　both　as　a　redox　catalyst　and　a　supporting　electrolyte;　in　this　manner　additional　conducting　salt　is　not　required.　A　wide　range　of　substrates,　including　aliphatic　or　aromatic　secondary　and　primary　amines,　as　well　as　aqueous　ammonia,　proved　to　be　compatible　with　the　protocol.　Scale-up　was　possible,　thereby　demonstrating　the　practicality　of　the　approach.　The　electrolytic　process　avoids　the　utilization　of　external　oxidants　or　corrosive　molecular　iodine　and　therefore　represents　an　environmentally　benign　means　by　which　to　achieve　the　transformation.
