A mechanistically divergent method is described that, employing a commercially available hypervalent iodine(III) reagent, generates alkoxy radicals from 1°, 2°, and 3° alcohols and allows their use in the functionalization of C(sp3)–H and C(sp2)–H bonds. This visible-light photoredox catalysis produces alkyl ethers via 1,5/6-hydrogen atom transfer or aryl ethers via 1,5-addition. This mild methodology

Abstract In solid state, the thermal rearrangement of bis(O-iodobenzoyl) peroxide which yields 1-(2'-iodobenzoyloxy)-1,2-benziodoxolin-3-one,is investigated by laser Raman spectroscopy. The intramolecular vibration spectra are used to characterize this chemical rearrangement. The phonon spectra obtained as a function of the rearrangement progress show that, in spite of the reported topotactic nature
