14 Friedel-Crafts Alkylation 14.1 Introduction Friedel-Crafts alkylation and acylation reactions are a special class of electrophilic aromatic substitution (EAS) reactions in which the electrophile is a carbocation or acylium ion. These reactions are highly useful in that they involve carbon-carbon bond...

傅-克烷基化(Friedel-Crafts Alkylation) 概要 利用路易斯酸催化,在芳香环上进行的亲电烷基化取代反应(SEAr)。 该反应的缺点是经常会生成多取代以及重排的副产物。特别是当R’-X为一级碳卤代的烷烃的时候,由于不能生成稳定的碳正离子,所以经常会同时发生自身瓦格纳-梅尔外因(Wagnar-Meerwein)重排反应。正由于这种...

The Friedel-Crafts Alkylation represents one of the six classes of electrophilic aromatic substitution reactions. The diversity and scope of Friedel-Crafts Alkylations is broad.
The meaning of FRIEDEL-CRAFTS REACTION is a synthetic reaction in organic chemistry in which anhydrous aluminum chloride acts as the typical catalyst.
