PROCESS:The compound of formula (1a) is prepared by reacting 1mol of the compound of formula (2) with 1-1.5mol of the compound of formula (3) (X is Br, Cl or I) in a solvent such as methanol in the presence of an acid acceptor (e.g. NaHCO3). When the molar ratio of the ...
Benzoic anhydride undergoes Friedel-Crafts acylation reaction with benzene over various ion-exchanged heteropoly acids to yield benzophenone. Purification Methods Free it from benzoic acid by washing with NaHCO3, then water, and drying. Crystallise it from *benzene (0.5mL/g) by adding just enough pe...

The intramolecular (and regioselective) delivery of an oxygen atom from this specie lead to a λ3-iodanyl intermediate which undergoes tautomerization and oxidatively collapses to produce an ortho-quinone derivative and 2-iodobenzoic acid (IBA), the only by-product of the reaction. The catecholic ...
