IntroductionFriedel-Crafts acylation is a specific example of a larger class of reactions calledelectrophilic aromatic substitutions. Electrophilic aromatic substitution is a type reactionin which an atom attached to an aromatic compound--usually a Hydrogen on a Benzenering--is replaced by an ...
is now mainly produced through the reaction of methylating agent of dimethyl sulfate with phenol in alkaline aqueous solution. Anisole is prone to start Electrophilic substitution reaction in aromatic nucleus, and condensed with formaldehyde to produce viscous oil or resin material, reacts with phosphor...

It is observed that shape selectivity effects prevail over electrophilic substitution and thermodynamic equilibrium effects in the formation of methylanisole isomers. However, the opposite is true for the distribution of cresol isomers. The kinetic analysis indicates that the contribution of unimolecular ...
cheap and green strategies is of fundamental signifi cance.Aryl iodides can undergo a series of homo-/cross-coupling reactions for the synthesis of important industrial chemicals and materials.Traditional methods require the electrophilic substitution on aromatic compounds by iodine or hypervalent iodine ...
