Pulse radiolysis of 1,1-diphenylethylene (DPE) in methanol in the presence of oxygen, as well as of 1,1-diphenyl-2-chloroethylene (DPE-2-Cl), 1,1-diphenyl-1-chloroethane (DP-1-Cl-Et) and 1,1-diphenyl-2-chloroethane (DP-2-Cl-Et) in methanol saturated with argon, was performed. The products formed under pulse-radiolysis conditions were also analysed. Spectroscopic and kinetic data of the corresponding
在氧气存在下在甲醇中对1,1-二苯乙烯(DPE)进行脉冲辐射分解,以及1,1-二苯-2-氯乙烯(DPE-2-Cl),1,1-二苯-1-氯乙烷(进行了在用氩气饱和的甲醇中的DP-1-Cl-Et)和1,1-二苯基-2-氯乙烷(DP-2-Cl-Et)。还分析了在脉冲辐射分解条件下形成的产物。给出了相应瞬态的光谱和动力学数据。在甲醇中确定的反应速率常数为k(e – s + O 2)=(2.0±0.1)×10 10 dm 3 mol –1 s –1,k(e – s + DPE-2-Cl)=(1.1 ±0.1)×10 10dm 3 mol –1 s –1,k(e – s + DP-1-Cl-Et)⩽1.5×10 10 dm 3 mol –1 s –1,k(e – s + DP-2-Cl-Et )=(1.3±0.2)×10 10 dm 3 mol –1 s –1,k(H + DPE-2-Cl)=(2.0±0
