o-Quinodimethane 3 is generated effectively by Krf excimer laser (248 nm) photolysis of 1,2-bis(phenoxymethyl)-, 1,2-bis(phenylthiomethyl)- and 1,2-bis(phenylselenomthyl)-benzene via a two-photon process; cycloaddition of 3 with several dienophiles gives corresponding adducts in a maximum yield of 48%.
通过 Krf 准分子激光(248 nm)光解 1,2-双(苯氧基甲基)-苯、1,2-双(苯硫甲基)-苯和 1,2-双(苯基硒甲基)-苯的双光子过程,可有效生成邻二甲基喹啉 3;3 与几种二烯烃进行环加成反应,可得到相应的加合物,最大产率为 48%。
