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.

The synthesis and spectral studies of A3B and A2B2 type porphyrins and their Pd(II) complexes are reported. The meso-positions on porphyrin macrocycle are substituted with pentafluorophenyl and N-butylcarbazole or triphenylamine groups. Pd(II) porphyrins displayed decent phosphorescence ~670 nm and are able to produce singlet oxygen by type II pathway, after photoirradiation. The calculated singlet oxygen quantum yields for Pd(II) porphyrins are (ΦΔ = 30%–63%). The catalytic application of Pd(II) porphyrins towards photoassisted aerobic oxidation of aromatic aldehydes to carboxylic acids is demonstrated.
