Induced Decomposition

The thermolysis of tert-butyl perpent-4-enoate 1 in THF led to several compounds; the main product, 5-(2-tetrahydrofuryl)-4-pentanolide (yield 42%) comes from an induced decomposition of the perester occurring with the addition of 2-tetrahydrofuryl radical to the double bond. A similar reaction was performed at a lower temperature, using butyl perdicarbonate as initiator, but did not define the mechanism (concerted or two-step). The thermolysis of 1 in ethers (THP, oxepane, 1,4-dioxane, dipropyl ether) appears to be a useful synthetic tool: several new γ-lactones have been obtained in this way.

Hydroxyl Hydrogen

tert-Butylazodiphenylcarbinol (Ph2C(OH)N=NCMe3, 3) decomposes in oxygen-free benzene by the unimolecular radical mechanism characteristic of most azo compounds. In benzene or in carbon tetrachloride, with or without air present, decomposition of 3 is also induced by radicals through abstraction of hydroxyl hydrogen in concert with the formation of nitrogen. Radicals which induce decomposition of 3 include trichloromethyl, tert-butyl, phenylthiyl, tert-butylperoxy and possibly oxygen. The failure of inhibitors like thiophenol to stop chain decomposition of 3 is interpreted in terms of the thermochemistry of induced decomposition.

Good Agreement

Allyl-tert-butyl peroxide decomposes thermally in toluene with kd = 1013.8 exp (−33200/θ) (s−1). Product studies show the reaction to be a mixture of homolysis and radical-induced decomposition, the latter involving both radical addition to C=C and allyl hydrogen abstraction by alkoxy radicals. Computer modelling of the system gives good agreement with the experimental results and suggests that the overall decomposition is about 50% homolysis.
