摘要
基于实验观察和反应物的MO计算,发现长波长光照下的S_(RN)1反应活性与电子加到ArX-LUMO的难易程度有关。由ArBr和碳负离子形成的基态电荷转移复合物的激发可能是S_(RN)1光诱导的主要通道。
Based on the experimental observations and MO calculation of the reactants, it was
found that the S_(RN) 1 reactivity followed the ease with which one electron could be added
to ArBr-LUMO. Excitation of the ground charge-transfer-complex formed from ArBr
and carbanion might represent a significant fraction of S_(RN) 1 photostimulation.
