Abstract

AbstractThe decomposition of tert‐butyl hydroperoxide by photochemically induced reactions in DMSOAbbreviations used: DMSO, dimethyl sulfoxide; DMSO‐d6, completely deuterium labelled dimethyl sulfoxide; cw‐ESR, continuous‐wave Electron Spin Resonance; u. v., ultra violet; DMPO, 5, 5‐dimethyl‐I‐pyrroline N‐oxide; TMPO, 3, 3, 5, 5‐tetramethyl‐l‐pyrroline N‐oxide. and water was investigated by cw‐e.s.r. spectroscopy. The products tert‐butylperoxyl, methyl and sulfur‐centered free radicals were identified. The tert‐butoxyl free radical is involved in the primary process as shown by time‐resolved e.s.r. technique. On the basis of directly identified radical species, a mechanism for the photochemically induced reactions of tert‐butyl hydroperoxide in DMSO is proposed. At concentrations below 0.8 mol · l−1 the radical formation from tert‐butyl hydroperoxide proceeds by cleavage of the OO bond rather than by hydrogen abstraction.
