Deals specifically with sulphenic acids and their derivatives and, like all books in Saul Patai's series, features commissioned chapters on theoretical and structural aspects, followed by sections on stereochemistry, synthesis, photochemistry and spectroscopy. Among the topics covered are analytical aspects of sulfenic acids and their derivatives; NMR and ESR of sulfenic acids; syntheses of sulfenic acids and esters, and of sulphenyl halides and sulphenamides; photochemistry and radiation; electrochemistry; metabolic pathways of sulfenic acids; and more.
