Charge-transfer interactions between 2-vinylnaphthalene (VN) in the excited singlet state and amines in the ground state significanty alter the product distribution in the photochemical reaction of VN, increasing the trans: cis ratio of 1,2-di(2-naphthyl)cyclobutane from 1 : 10 in the absence of amines to ca. 2 : 1 in the presence of 1,4-diazabicyclo[2.2.2]octane.
处于激发态的2-乙烯基萘(VN)与处于基态的胺之间的电荷转移相互作用显着改变了VN的光化学反应中的产物分布,从而增加了1,2-二(2-萘基)的反式:顺式比环丁烷在没有胺的情况下从1:10到大约 在1,4-二氮杂双环[2.2.2]辛烷存在下为2∶1。
