Reaction of secondary amines with 1-tert-butylperoxy-1,2-benziodoxol-3(1H)-one (2) undergoes dehydrogenation to afford imines in the presence of K2CO3, while oxidation of tertiary amines without base produces tert-butylperoxyamino acetals.

Photolysis of (E)-azoisobutane and dialkyl and diaryl disulfides in oxygenated 2-methylbutane at temperatures below 230 K results in a very low photostationary state of peroxyl radical, because of the high efficiency of the mixed termination reaction to form sulfanylperoxide and peroxycyclohexadienethione.Surprisingly, after photolysis is stopped there is an immediate threefold rise in the peroxyl radical concentration.This post-illumination dark reaction is interpreted and accurately modelled using an algorithm, by assuming an irreversible decomposition of the sulfanylperoxide or peroxycyclohexadienethione to alkoxyl and other radicals.Spin traps have been used to confirm the nature of the radicals involved in many of the proposed reactions and to give a measure of radical concentrations under various experimental conditions.Values of the rate parameters for a number of these reactions have been measured and Arrhenius parameters E2 = 34 kJ mol-1, A2 = 106 s-1, E2 = 14 kJ mol-1, A2 = 102.4 s-1 determined for the decomposition of phenyl and tert-butyl sulfanylperoxides, respectively.The low A factor for tert-butyl sulfonylperoxide is probably associated with a tight, four-membered ring transition state with a loss of internal rotations about partially formed sulfur-oxygen double bonds and accompanying solvent orientations about the more dipolar S=O bond.The decomposition of the phenyl analogue occurs by scission of O-O links in para and ortho substituted peroxycyclohexadienethione.
Reactions of Oxygenated Radicals in the Gas Phase. Part 14. Reactions of t-Butylperoxyl Radicals

The photo-oxidation of trans-2,2'-azoisobutane has been studied between 313 and 393 K.The principal products are acetone, t-butyl alcohol, t-butyl hydroperoxide, and formaldehyde.The yields of hydroperoxide and formaldehyde come to a limiting value during photolysis.Detailed analyses of products were carried out at different temperatures and total pressures.Further experiments were performed in which t-butyl hydroperoxide was added.The reaction was simulated over this wide range of conditions.The importance of reactions between the various alkylperoxyl radicals is emphasised.
