  Laser-flash photolysis of naphthyl diselenides; reactivities of naphthylseleno radicals

  摘要：

  Transient absorption spectra of 1-naphthylseleno (1-NaphSe(.)), and 2-naphthylseleno (2-NaphSe(.)) radicals, which are generated by laser-flash photolysis of the corresponding diselenides, were observed. The reactions of 1-NaphSe(.), and 2-NaphSe(.) with 2-methyl-1,3-butadiene and alpha-methylstyrene were investigated by following the decay rates of these seleno radicals. By both steady-state and laser-flash photolysis, it is proved that these seleno radicals add to alkenes in a reversible manner. The reaction rate constants for such reversible addition reactions were determined by conducting the reaction in the presence of O(2), which traps selectively the carbon-centered radicals formed by the addition reaction of the seleno radicals to the alkenes. The reactivity of 2-NaphSe(.) is higher than that of 1-NaphSe(.), both of which are less reactive than PhSe .. These reactivities were interpreted with the properties of SOMO calculated by MO method.
