金属铜催化不对称friedel-crafts alkylation reactions 铜催化不对称Friedel-Crafts烷基化反应是Friedel-Crafts反应的一种特殊形式,在有机合成中扮演了重要的角色。在反应中,铜作为催化剂,能够促进芳族烃或烷基卤化物与芳香族化合物之间发生取代反应,从而实现不对称烷基化。 这种反应可以通过使用手性诱导剂来获得立体异构体...
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.
A Friedel-Crafts reaction is an organic coupling reaction involving an electrophilic aromatic substitution that is used for the attachment of substituents to aromatic rings. The two primary types of Friedel-Crafts reactions are the alkylation and acylation reactions. These reactions were developed in the...

The meaning of FRIEDEL-CRAFTS REACTION is a synthetic reaction in organic chemistry in which anhydrous aluminum chloride acts as the typical catalyst.
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...
2.4.2 Friedel–Crafts reaction A surfactant combined with a Lewis acid was found effective by Roelfes and co-workers in catalyzing the Friedel–Crafts alkylation of heteroaromatic compounds in water (Scheme 6) [116]. Scandium(III) triflate was used as catalyst and SDS as the micelle forming ag...
