The FriedelCrafts- type carboxylation of arenes has been achieved by activating CO2 with silylium borates. The reaction exhibits broader substrate applicability than does our previously reported AlX3/R 3SiX-mediated carboxylation.

Method for preparing 2, 4, 6-trimethylbenzoic acid from mesitylene and carbon dioxide
-
Paragraph 0019-0030, (2021/04/17)
The invention discloses a method for preparing 2, 4, 6-trimethylbenzoic acid from mesitylene and carbon dioxide. The method comprises the step of synthesizing 2, 4, 6-trimethylbenzoic acid by taking mesitylene as a raw material, lewis acid as a catalyst and carbon dioxide as a carbon source under certain pressure and temperature. Oxidants such as potassium permanganate are not used. The method has the highest atom utilization rate of the synthesis reaction, and has atom economy and good industrial application prospect.

Direct catalytic oxidation of alcohols to carboxylic acids is very attractive, but economical catalysis systems have not yet been well established. Here, we show that a pure inorganic ligand-supported chromium compound, (NH4)3[CrMo6O18(OH)6] (simplified as CrMo6), could be used to effectively promote this type of reaction in the presence of CO2. In almost all cases, oxidation of various alcohols (aromatic and aliphatic) could be achieved under mild conditions, and the corresponding carboxylic acids can be achieved in high yield. The chromium catalyst 1 can be reused several times with little loss of activity. Mechanism study and control reactions demonstrate that the acidification proceeds via the key oxidative immediate of aldehydes.
