烯丙胺与C60的热引发[3+2]环加成反应
A Thermoinduced [3+2] Cycloaddition of Allylic Amines with C60
【摘要】 烯丙胺类化合物与C6 0 在热引发下发生新型的 [3 + 2 ]环加成反应 .反应有较好的立体选择性 .该反应可能经过了热引发的烯丙胺的单电子转移过程 ,产生烯丙基自由基 ,并进一步与C6 0 加成及环化 .文中C6 0 衍生物的结构均经过谱学方法确证
【Abstract】 A novel [3+2] cycloaddition reaction of allylic am ines with C 60 was found. Good stereoselectivity in this reaction was obser ved. A possible mechanism involving thermoinduced single electron transfer of al lylic amines and radical cycloaddition was proposed. The structures of the cyclo addition products were characterized by spectroscopic means.
