摘要: 本文通过一系列卤代烃与苯的付氏反应的ESR谱,研究了自由基物种的生成机理:它们起因于Lewis酸对由Scholl反应所生成的9,10-二取代蒽进行单电子氧化,并建立了一种生成9,10-二取代蒽自由基正离子的简单方法。首次报道了一个新自由基正离子1,2,3,4,5,6,7,8-八氘蒽的ESR谱。

关键词: 付氏反应, ESR谱, 自由基正离子

Abstract: Friedel-Crafts reactions of a series of alkyl halides with benzene gave well-resolved ESRspectra which originated from 9,10-disubstituted anthracene radical cations formed through one-electron oxidation of the parent compounds by Lewis acid. Asimple method for the formation of 9,10-disubstituted anthracene radical cations has been developed and an ESRspectrum of a new radical cation 1,2,3, 4,5,6,7,8-octadeuteroanthracene is reported.

Key words: Friedel-Crafts reaction, ESR spectrum, Radical cations
