Acetonyl radicals created by action of di-t-butylperoxide on acetone (molar ratios acetone/acetylenic compound/DTBP = 20/1/0.2; 150°C; 3h) add to acetylenic compounds and lead to the formation of 1/1 adducts in low to moderate yields. 2/1 adducts ar

Addition of acetonyl radicals to 1-octyne leads to the formation of 1/1 adducts. Besides the normal product, appear two kinds of cyclic derivatives. Formation of the latter is explained by hydrogen shifts in the transient vinyl radical. 1,5-hydrogen

Thermolyses of dicyclohexyl carbonyl peroxide have been performed in organic solutions of t-butyl pent-4-enyl peroxide or t-butyl perpent-4-enoate in order to study the induced decomposition by cyclohexyl radicals of these peroxides. Induced decompos

The reaction of N,N′-carbonyldiimidazole with but-3 enoic acid did not lead to the expected azolide; its rearrangement into conjugated isomer was followed by imidazole addition to the double bond. These two reactions make inefficient this preparati

Resume La photooxygenation des γ- et δ-pyronenes, realisee pour la premiere fois, conduit classiquement a un hydroperoxyde, un hydroperoxy-peroxyde, et un endoperoxyde respectivement. La reactivite de ces peroxydes est etudiee. Ils conduisent a des

The decomposition of allylic peroxides in methyl thioglycolate always leads to both epoxide and adduct peroxide. According to the nature of the allylic chain, either epoxide or peroxide is the predominant product, if not the only one. It is the first
