The formation of acenaphthene 4 by laser-jet photolysis of 1,8-bis(phenoxyrmethyl)-(1a), 1,8-bis(phenylthiomethyl)-(1b) and 1,8-bis(phenylselenomethyl)-naphthalene (1c) strongly depends on the hetroatom of the leaving group; the increasing order of naphthalene consumption was 1câ1b > 1a, whereas that for the formation of 4 was 1c > 1a > 1b.
通过激光喷射光解 1,8-双(苯氧甲基)-(1a)、1,8-双(苯
硫甲基)-(1b) 和 1,8-双(苯
硒甲基)-
萘 (1c),
苊 4 的生成与离去基团的喉原子有很大关系;
萘消耗量的递增顺序为 1câ1b > 1a,而 4 的生成顺序为 1c > 1a > 1b。
