Products analyses of the thermolyses of the peroxides CH2=CH-(CH2)n OOtBu, , (n= 1-5) showed that an induced decomposition of occured for n=l,2,3,4. Free radical additions of THF, carbon tetrachloride, bromotrichloromethane to have been performed at lower temperature ; they allowed, through the isolation of an adduct peroxide, at least in one case for each peroxide, to prove that a two-steps mechanism
过氧化物CH 2= CH-(CH 2)n OOtBu ,(n = 1-5)的热解的产物分析表明,在n =1、2、3、4时发生了诱导的分解。THF,四氯化碳,溴三氯甲烷的自由基加成已在较低温度下进行;他们通过分离过氧化物加合物,至少在每种情况下对一种过氧化物进行了分离,证明了两步机理(自由基Z·加到双键上,分子内均质置换)参与了诱导的三价氧的分解。。可以估计这些S H i反应的速率常数的数量级。
