Owing to its peroxyester group, O,O-tert-butyl and O-vinyle peroxycarbonate may act as a free radical initiator in solution, but also, due to the presence of the vinylic insaturation, as a substrate for free radical addition reactions. - In such solvents as cumene which give free radicals unable to add to the double bond, the peroxycarbonate merely behaves as a vinyloxy radicals generator.It is thus possible to observe these radicals reacting either as formylmethyl radicals or as acetyl radicals. - In solvents such as cyclohexane which give free radicals able to add to the double bond, the reaction results in the substitution of formylmethyl groups to labile hydrogens of the solvent. - By applying the reaction to such compounds as ketones, ethers, acids and their derivatives, we could obtain γ-functional aldehydes (γ-ketoaldehydes, γ-oxaaldehydes and derivatives of succinaldehydic acids).These products are often difficult to prepare by other routes and until now only some of them have been described.
