Structures and Optical Absorption of Some Sulfuranyl Radicals in Solution

Article abstract of DOI:10.1021/jo00214a021

Optical absorption spectra due to the sulfuranyl radicals (t-BuO)3S (2), (3), and (4) were detected by the use of laser flash photolysis.Both 2 and 3 have ? structures and their optical spectra are significantly blue-shifted with respect to that of 4 which has a ? or ?* structure.The results suggest that optical absorption spectroscopy may be a useful guide in the assignment of the electronic structures of sulfuranyls.
