Several 2-(arylmethyl) derivatives of 3,6-dimethyl- and 3,4,5,6-tetramethylbenzonitriles have been prepared in good yields most likely by a tandem addition-rearrangement reaction of the appropriate bromoarene and arylacetonitrile under aryne-forming conditions. Additionally, several 2-aryl-2-(1,4-dimethyl-2-naphthyl)acetonitriles were obtained by the usual aryne mechanism from the reaction of 2-bromo-1,4-dimethylnaphthalene and arylacetonitriles with lithium tetramethylpiperidide.
3,6 二甲基和 3,4,5,6 四甲基苯腈的几种 2-(芳基甲基)衍生物以良好的收率制备出来,很可能是通过适当的溴芳烃和芳基乙腈在芳炔形成条件下的串联加成-重排反应制备出来的。此外,在 2-溴-1,4-二甲基萘和芳基乙腈与四甲基哌啶锂的反应中,通过通常的芳香族机理得到了几个 2-芳基-2-(1,4-二甲基-2-萘基)乙腈。
