Etude de la thermolyse de peroxyacétals et peroxycétals

Thermolysis of organic peroxides in solution

“…The decomposition of diperoxyacetals is accompanied by the transient formation of peroxy esters 192 The decomposition of aromatic peroxy acetals occurs in accordance with the same scheme, i.e., with the formation of peroxybenzoates as intermediates: 193 Under these conditions, the contribution of other parallel conversions of the initially formed radical increases.…”

Functional transformation of aldehydes and ketones via homolytic induced decomposition of unsaturated peroxy acetals and peroxy ketals

“…The formation of this compound could be attributed to the disproportionation, in the solvent cage, of the oxyl radicals formed by the spontaneous decomposition of the unsaturated peroxy acetal. 10 Performing the same reaction at room temperature with initiation by BEt 3 -O 2 (a BEt 3 solution in hexane was added slowly to the mixture of the other reactants prepared under air, the needle of the syringe being in the liquid) confirmed this origin since no methyl dodecanoate was detected under these conditions and 1-chloro-…”
