Intramolecular homolytic displacements. Part 29:† induced decompositions of 4,5-ethylenic peroxyketals
Abstract
Thermolysis of a free radical initiator in solutions of hydrogen donor solvents such as cyclohexane, 1,4-dioxane and methyl isobutyrate, generated radicals by hydrogen abstraction of the solvent that were capable of adding to the unsaturated bond of 4,5-ethylenic peroxyketals. The adduct radical obtained led to 2-alkoxytetrahydrofuran by an SHi on the O–O bond.
