Electron spin resonance spectra of selenuranyl radicals R2Se–X
Abstract
E.s.r. spectra assigned to the σ* selenuranyl radicals R2Se[graphic omitted]X (R = alkyl or aryl) are detected in solution during photochemical generation of X·[CF3S·, R′C(O)S·, Me3CO·, or Me3SiO·] in the presence of dialkyl or alkyl aryl selenides.
