Dilauroyl peroxide

The extent of decarboxylation primarily depends on temperature, pressure, and the stabihty of the incipient R- radical. The more stable the R- radical, the faster and more extensive the decarboxylation. With many diacyl peroxides, decarboxylation and oxygen—oxygen bond scission occur simultaneously in the transition state. Acyloxy radicals are known to form initially only from diacetyl peroxide and from dibenzoyl peroxides (because of the relative instabihties of the corresponding methyl and phenyl radicals formed upon decarboxylation). Diacyl peroxides derived from non-a-branched carboxyhc acids, eg, dilauroyl peroxide, may also initially form acyloxy radical pairs however, these acyloxy radicals decarboxylate very rapidly and the initiating radicals are expected to be alkyl radicals. Diacyl peroxides are also susceptible to induced decompositions ...

Diacyl or diaroy] peroxides (36, R- alkyl or aryl respectively) are given specific coverage in reviews by Fujimori,141 Bouillion et c//.,14 and Hiatt.14j They are sources of acyloxy radicals which in turn are sources of aryl or alkyl radicals. Commercially available peroxides of this type include dibenzoyl peroxide (BPO), didodecanoyl or dilauroyl peroxide (LPO), didecanoyl peroxide (42) and succinic acid peroxide (43).

The reaction of verdazyls (111) with diacyl peroxides, such as benzoyl peroxide, dilauroyl peroxide, perbenzoic acid and substituted perbenzoic acids has received considerable attention (76TL1893, 78ZOR2471, 78MI22101). One mole of the radical always consumes three moles of the peroxide. The first product is the verdazylium salt (113) which is then transformed into the Af-formylformazan (112). 

A tin-free radical cyclization of the xanthate 272 using dilauroyl peroxide (DLP), as the radical initiator, in chlorobenzene was used to give the 5//-pyrido[2,3-A azepin-8-one 273 (Scheme 35) <20040L3671>. The xanthate 272 was also made by an intermolecular free radical addition to allyl acetate, using the xanthate 271, as the radical precursor. Somewhat surprisingly in this latter case, intramolecular free radical attack on the pyridine ring did not take place. 

The reduction of the 6-bromohex-l-ene was performed by heating at 80°C a degassed solution of dilauroyl peroxide (0.004 M), triethylsilane (1.5 M), unsaturated bromide (0.0386M), dodecanethiol ( 0.003 M) or thiol supported polymer(0.002 M) in heptane.
