An invaluable text for synthetic chemists in the pharmaceutical, agrochemical, plastic and detergent industries, this book provides a detailed, up-to-date account of the reactions of chlorosulfonic acid with aliphatic, aromatic and heterocyclic compounds. Examples include: medicinal agents such as sulfonamide antibacterials and diuretics; disinfectants (chloramine and dichloramine T); pesticides like sulfonylurea; carbamate herbicides and aryl sulfone acaricides; synthetic sweeteners, e.g. 1). The antibacterial action was found to be generally confined to derivatives of sulfanilamide ( p-aminobenzenesulfonamide) of the type depicted by structure 1 with variations in R 1 and R 2; in the majority of the sulfa drugs the substituent R 1 = H, but there is considerable variation in the other substituent, R 2.
