Question

Friedel craft alkylation of toluene with vinyl chloride

Answer 1

1-Arylalkenyl sulfides were produced in good yields by treatment of 1-(phenylthio)vinyl chlorides with arenes in the presence of aluminum chloride or ethylaluminum dichloride. The stereoselectivity indicated that the reaction is kinetically controlled process.

The Friedel-Crafts reaction of 1-(phenylthio)vinyl chlorides (1) with arenes proceeded in the presence of AlCl3 or EtAlCl2 to give 1-arylalkenyl sulfides (2). The stereoselectivity indicated that the reaction is a kinetically controlled process.

Answer 2

Hey Dear,

◆ Friedel craft alkylation -

• It's aromatic nucleophilic substitution reaction.
• Presence of methyl group in ring favours Friedel craft reaction in toulene.
• Toluene on Friedel craft reaction with vinyl chloride gives 4-methyl-styrene.

Ph-CH3 + CH2=CH-Cl --> CH3-Ph-CH=CH2 + HCl

Hope this helped you. Thanks for asking questions.
