to form the carbon skeleton. & © 2003-2020 Chegg Inc. All rights reserved. Therefore, these Lewis acid ILs may be suitable candidates for the synthesis of benzophenone and its derivatives through a Friedel–Crafts acylation reaction. In these reaction systems, good to excellent yields (up to 97%) of acylation products were obtained in a short reaction time. 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.

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 … Once in hand, you could oxidize benzaldehyde to benzoic acid. https://doi.org/10.1016/j.catcom.2007.02.023. source of the two aromatic rings. Privacy Among them, BmimCl–FeCl3 showed much higher catalytic activity than that observed for the other two ILs, and in conventional organic solvents. View desktop site. Benzophenone can be synthesized by converting benzene into two separate reacting partners which are then brought together to form the carbon skeleton.

Efficient synthesis of benzophenone derivatives in Lewis acid ionic liquids. Benzophenone is produced by the copper-catalyzed oxidation of diphenylmethane with air. Show all the steps needed to synthesize benzophenone starting from benzene as the only source of the two aromatic rings. In either case, with benzoic acid in hand, you can procede as you've indicated, on to benzophenone. ScienceDirect ® is a registered trademark of Elsevier B.V.
