A 1:1 charge-transfer (CT) complex between 1-benzyl-1,4-dihydronicotinamide (BzlNH) and chloranil was isolated from a benzene solution of these reactants (hνCT =1.70 eV, λmax = 730 nm). The transient CT band was observed also in the hydride transfer from BzlNH to chloranil in MeCN. The decay of the CT band coincided with the formation of the product, tetrachlorohydroquinone anion.
从这些反应物的苯溶液中分离出 1-苄基-1,4-二氢烟酰胺 (BzlNH) 和
氯苯醌之间的 1:1 电荷转移 (CT) 复合物 (hνCT =1.70 eV, λmax = 730 nm)。在 MeCN 中从 BzlNH 到
氯苯醌的
氢化物转移中也观察到了瞬态 CT 带。CT 带的衰减与产物四
氯氢醌阴离子的形成同时发生。
