WebA reação clássica de alquilação de Friedel-Crafts é uma reação de substituição eletrofílica catalisada que surge de um ataque de carbocátion na dupla ligação de uma molécula de areno. O catalisador para essa reação é tipicamente um cloreto, como o AlCl3, que atua como um agente de condensação. WebA 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 …

WebAluminum trichloride (AlCl3) impregnated molybdenum oxide heterogeneous nano-catalyst was prepared by using simple impregnation method. The prepared heterogene The Friedel–Crafts reactions are a set of reactions developed by Charles Friedel and James Crafts in 1877 to attach substituents to an aromatic ring. Friedel–Crafts reactions are of two main types: alkylation reactions and acylation reactions. Both proceed by electrophilic aromatic substitution. See more With alkyl halides Friedel–Crafts alkylation involves the alkylation of an aromatic ring. Traditionally, the alkylating agents are alkyl halides. Many alkylating agents can be used instead of alkyl … See more This reaction is related to several classic named reactions: • The acylated reaction product can be converted into the alkylated product via a Clemmensen See more Friedel–Crafts acylation involves the acylation of aromatic rings. Typical acylating agents are acyl chlorides. Acid anhydrides as well as carboxylic acids are also viable. A typical Lewis acid catalyst is aluminium trichloride.
