Direct irradiation of 1,1,2-triarylcyclopropanes in alcohol resulted in the formation of all possible products arising from trimethylene biradicals, while DCB-sensitized irradiation gave a novel ”anti-Markownikoff“ addition product of alcohol almost exclusively. In order to get insight into the nature and fate of intermediates in the reactions, the effects of nucelophiles and aryl substituents are
1,1,2-三芳基
环丙烷在醇中的直接辐照导致所有可能的三亚甲基双自由基产物的形成,而 DCB 敏化辐照几乎完全产生了一种新型的“抗 Markownikoff”醇加成产物。为了深入了解反应中中间体的性质和归宿,研究了亲核试剂和芳基取代基的影响。
