In Part I of this Account, the utility of [hydroxy(sulfonyloxy)iodo]benzenes, PhI(OH)OSO2R, and closely related sulfonyloxyiodinanes for the oxysulfonylation, aryliodination, and oxidation of organic molecules is reviewed. Not only is the work from the research groups of the principal authors covered, but also that of other major researchers in the field. These hypervalent iodine reagents have been employed for the preparation of α-sulfonyloxy carbonyl compounds (ketones, esters, lactones), vic-ditosyloxyalkanes, 1,4-disulfonyloxyalkenes, tosyloxylactones, bislactones, ketolactones, isoflavones, and alkynyl- and vinyliodonium salts. The functionalization of cubanes, the direct conversion of carboxamides to alkylammonium tosylates and various oxidative rearrangements are also described. Some underlying and unifying mechanistic interpretations are presented with particular emphasis on the stereo- and regiochemistry attending the aforementioned transformations. In Part II one of the authors (GFK) documents the role of serendipity in a number of discoveries achieved by his group in this area. Part 1.
