Friedel-Crafts acylation reaction was studied under mild conditions using hierarchical HY zeolite samples prepared through surfactant mediated technology, in the presence of NH 4 OH, using CTAB or DTAB as surfa
The meaning of FRIEDEL-CRAFTS REACTION is a synthetic reaction in organic chemistry in which anhydrous aluminum chloride acts as the typical catalyst.
9.4.1 Friedel–Crafts alkylations and acylations The Friedel–Crafts reaction is one of the most important reactions in organic chemistry (Clark, 1994). The newer type of metal ion-exchanged Mt, MCl2-Mn +-Mt (M = Ni, Cu, Zn; n = 2) catalysed the benzylation of benzene (Scheme 9.3...

the Friedel-Crafts reaction has been extended to include a range of compounds resulting from the alkylation or acylation of aliphatic hydrocarbons containing double bonds. Thus, the Friedel-Crafts alkylation reaction has proven value to the synthesis of a broad range of important polymers via polymer...
The Friedel‐Crafts acylation reaction, another example of an electrophilic aromatic substitution reaction, is similar to the Friedel‐Crafts alkylation reaction

9. The Mechanism Of The Friedel-Crafts Acylation Reaction So how does the Friedel-Crafts acylation reaction work? As with FC alkylation, the first step is activation of the electrophile. Lewis acid coordinates to the halogen, and departure of the halogen (as AlCl4–) results in a fairly stab...
