primary, secondary, and tertiary aliphatic amines to give substitution products in which one of the cyano groups was replaced by the amine at α-CH position or by an alkyl group of the amine. o-Dicyanobenzene reacted similarly, but the meta-isomer did not react under similar conditions. The rates of the fluorescence quenching of p-dicyanobenzene with the amines are close to the diffusioncontrolled rate
辐照后,对二氰基苯与脂肪族伯胺、仲胺和叔胺反应生成取代产物,其中一个氰基被 α-CH 位的胺或胺的烷基取代。邻二氰基苯反应类似,但间位异构体在类似条件下不反应。对二氰基苯与胺的荧光猝灭速率接近于扩散控制速率,但在某种程度上取决于胺的电离电位。当取代产物被辐照时,得到相应的烷基化产物。这些反应的机制已经通过使用诸如 MeOH(MeOD) 等质子供体进行了研究。在这些研究的基础上,涉及电荷转移的新光化学反应,
