Transition-Metal-Free Regiospecific Aroylation of Nitroarenes Using Ethyl Arylacetates at Room Temperature

A novel regiospecific C(sp3)-C(sp2) coupling between ethyl arylacetates and nitroarenes has been developed to deliver biaryl ketones in excellent yields. The protocol is metal-free, mild, and compatible with a number of functional groups on both of the reacting partners.

Diarylketone preparation method

The invention discloses a diarylketone preparation method. According to the method, substituted nitrobenzene and aromatic acetic ester are dissolved in an organic solvent, alkali is added, the mixture is subjected to a reaction in the air or oxygen atmosphere at the temperature of 10-60 DEG C for 0.5-24 h, and diarylketone is obtained; the mole ratio of substituted nitrobenzene to aromatic acetic ester is (0.5:1)-(5:1), and the mole ratio of alkali to aromatic acetic ester is (1:1)-(5:1). The method overcomes defects caused by the adoption of strong acid or expensive metal reagents or strong oxidizers and the like in the prior art and has the advantages as follows: 1) with air as an oxidizer, use of strong or expensive chemical oxidizers is avoided; 2) no transition metal catalysts are used, so that the condition that heavy metal ions are left in a product is avoided; 3) without inductive groups, surplus steps of introduction of the inductive groups and removal of the inductive groups are avoided; 4) acylation of ortho positions or para positions of nitro-aromatic compounds is directly realized, which cannot be realized with a classic Friedel-Crafts acylation method. The synthesis method plays an important role in preparing diarylketone, particularly industrial production of acylation products of ortho positions or para positions of the nitro-aromatic compounds.

Synthesis of Diaryl Ketones Catalyzed by Al2O 3-ZrO2/S2O82- Solid Superacid

The acylation of a variety of aromatic compounds with benzoyl chloride or its derivatives and catalytic amounts of Al2O3-ZrO 2/S2O82- solid superacid affords the corresponding diaryl ketones in good to excellent yields 75-93% at appropriate temperature.
