A research team at Johannes Gutenberg University Mainz (JGU) in Germany has developed a completely new, environmentally friendly electrochemical procedure for producing sulfonamides rapidly and inexpensively. Sulfonamides are used in many drugs including antibiotics and Viagra as well as in agrochemicals and dyes, which makes them an important class of molecules for the pharmaceutical and chemical industries. While to date, it has been necessary to use corrosive chemicals, high temperatures, and expensive metal catalysts to produce sulfonamides, the new method requires only cheaper starting materials, electrical current, and largely safe solvents. The researchers recently reported their findings in the journal Angewandte Chemie International Edition.
