Friedel-CraftsAlkylation反应背景 •1877年，C.Friedel和J.M.Crafts用在苯中的薄铝条处理戊基氯，观察到苯戊基的结构。后来发现烷基氯与苯的反应很普遍，而且三氯化铝被确认是催化剂。以Lewis酸做催化剂，以各种烷基化试剂（烷基氯，烯烃，炔烃，醇）取代芳基和脂肪基的反应叫做Friedel-Crafts烷基化反应。反应通式 ...
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.
Friedel Crafts Acylation have several advantages over Friedel Craft Alkylation. These advantages include a better control over the reaction products and also the acylium cation is stabilized by resonance so no chances of rearrangement. Using Clemmensen reduction, the ketones made can be reduced to alk...
Why is Friedel craft acylation better than alkylation? Acylation is preferred over alkylation in Friedel craft reaction. Because In the acylation, the acyl group being an electron-withdrawing group reduces the electron density hence further electrophilic substitution is prohibited. The carbon chain of ...

The Friedel-Crafts reaction is a typical electrophilic substitution reaction in the aromatic nucleus; the role of the catalyst amounts to the generation of an attacking particle—an alkyl or acyl cation. Examples are given below of the interaction of benzene with the ethyl chloride and the acid ...
Friedel-Crafts alkylation reaction: Friedel craft alkylation reaction is a reaction where there is a reaction between benzene and alkyl halide which results in the formation of alkylbenzene. This reaction takes place...
