Therefore, these Lewis acid ILs may be suitable candidates for the synthesis of benzophenone and its derivatives through a Friedel–Crafts acylation reaction.

In this paper, we report the results on Friedel–Crafts acylation of benzene or mono-substituted benzene with benzoyl chloride or phenyl acetyl chloride in ILs of BmimCl–FeCl 3 , BmimCl–ZnCl 2 and 1-butyl-3-methylimidazolium … View desktop site. In either case, with benzoic acid in hand, you can procede as you've indicated, on to benzophenone. into two separate reacting partners which are then brought together Once in hand, you could oxidize benzaldehyde to benzoic acid. & An alternate approach would be to 1) brominate benzene to form bromobenzene, 2) form the Grignard reagent with magnesium and 3) react it with carbon dioxide to produce benzoic acid. Benzophenone can be synthesized by converting benzene into two separate reacting partners which are then brought together to form the carbon skeleton. Copyright © 2007 Elsevier B.V. All rights reserved. This method features high yield, a simple product isolation procedure, ILs reusability and reduced waste discharge, thus rendering this catalytic system both efficient and environmentally friendly. Show all the steps needed to synthesize benzophenone starting from benzene as the only source of the two aromatic rings. By continuing you agree to the use of cookies. Show all the steps to form the carbon skeleton. Show all the steps needed to synthesize benzophenone starting from benzene as the only source of the two aromatic rings. Among them, BmimCl–FeCl3 showed much higher catalytic activity than that observed for the other two ILs, and in conventional organic solvents. Benzophenone is produced by the copper-catalyzed oxidation of diphenylmethane with air. Benzophenone and its derivatives were prepared via Friedel–Crafts acylation reactions using ionic liquids (ILs) of BmimCl–FeCl3, BmimCl–AlCl3 and BmimCl–ZnCl2 as dual catalyst–solvent. | Benzophenone can be synthesized by converting benzene into two separate reacting partners which are then brought together to form the carbon skeleton.
