and related substrates, an oxazole-based superelectrophile is found to be significantly more reactive than a related monocationic species. Theoretical calculations estimate that the lowest unoccupied molecular orbital (LUMO) for the superelectrophile is about 4 eV lower in energy than the LUMOs of comparable monocations. When the oxazole-based superelectrophile is reacted with ferrocene, a dimeric product
在与苯和相关底物的反应中,发现基于恶唑的超亲电试剂比相关的单阳离子物质更具反应性。理论计算估计,超亲电体的最低未占分子轨道 (LUMO) 的能量比类似单阳离子的 LUMO 低约 4 eV。当基于恶唑的超亲电试剂与二茂铁反应时,以高产率形成二聚产物。二聚化是通过双阳离子超亲电试剂和二茂铁之间的单电子转移反应发生的,然后是自由基阳离子的偶联。
