Symmetrical saturated and unsaturated primary dialkyl peroxides 1 were prepared in a phase-transfer reaction by direct action of potassium superoxide, tetraethylammonium bromide and alkyl bromide in dimethylformamide solution. Applicability of the method to the preparation of unsymmetrical dialkyl peroxides was demonstrated by the example of butyl octyl peroxide (2). Yields generally exceeded 80% for symmetrical dialkyl peroxides with total carbon numbers above 12 carbon atoms. Peroxide content of the isolated dialkyl peroxides generally exceeded 90%.

The UV irradiation of aromatic alcohols leads to the formation of several products: carbonyl compounds, ethers, α-glycols and tetra-aryl-1,4-dioxanes.The photoformation of α-glycols is qualitatively and quantitatively compared to the photoreduction of the carbonyl compounds.It is noteworthy that the glycols are formed with a stereochemistry very different depending upon whether the substrate is an alcohol or a carbonyl compound.The structure, configuration and conformation of the 1,4-dioxanes obtained are studied as well as their origin.Other aspects of the photochemistry of the alcohols are analyzed using hydroperoxides as model substrates.
