It is shown that in the laser jet (LJ) mode (argon ion laser) the benzhydryl phenyl ketone (1) undergoes a two-photon reaction in CCl 4 to yield benzhydryl chloride. The one-photon products are 1,1,2,2-tetraphenylethane (4), benzophenone, and 1,1,1-trichloro-2,2-diphenylethane (4). In methanol, on the other hand, our results suggest even a three-photon reaction in which benzhydryl methyl ether (5)
结果表明,在激光喷射 (LJ) 模式(氩离子激光)下,二苯甲基苯基酮 (1) 在 CCl 4 中发生双光子反应生成二苯甲基氯。单光子产物是 1,1,2,2-四苯基乙烷 (4)、二苯甲酮和 1,1,1-三氯-2,2-二苯基乙烷 (4)。另一方面,在甲醇中,我们的结果甚至表明,除了单光子产物 3 和二苯甲酮之外,还产生了二苯甲基甲基醚 (5) 的三光子反应。三光子与一光子乘积的比率,即 5 比 3,取决于波长(333 或 351 nm)
