The antibiotic Prontosil, developed by Bayer Pharmaceuticals in 1932, was used in saving the life of President Roosevelt's son from severe strep throat in 1936. Protonsil consists of two nitrogens bonded together in a double bond. The left nitrogen is bonded to a benzene ring where the para position contains a sulfur double bonded to two oxygen atoms and single bonded to N H 2. The right nitrogen is bonded to a benzene ring where one ortho and the para position each have an N H 2 substituent. substituent Prontosil is an azo dye, which can be prepared from an aryldiazonium ion and an aromatic compound. Draw the structures of the diazonium ion and the coupling component for this drug.
