acts as an efficient photocatalyst. The studies on the quantum yields and fluorescence quenching of AcrH+ by alkylbenzenes as well as the laser flash photolysis have revealed that the photochemical reactions of AcrH+ with alkylbenzenes in both the absence and presence of oxygen proceed via photoinduced electron transfer from alkylbenzenes to the singlet excited state of AcrH+ to produce alkylbenzene
在含有
H2O 的脱气
乙腈中,在可见光照射下,烷基苯与 10-甲基
吖啶离子 (AcrH+) 的加成有效地发生,选择性地产生 9-烷基-10-甲基-
9,10-二氢吖啶。另一方面,在脱气
乙腈中,在
高氯酸存在下,AcrH+ 与烷基苯的光
化学反应产生 10-甲基-
9,10-二氢吖啶,同时烷基苯氧化成相应的
苯甲醇。当 AcrH+ 充当有效的光催化剂时,烷基苯的光氧化也在
氧气存在下发生。
