CO2 fixation into electron-deficient aromatic C–H bonds proceeds with the combined Br?nsted bases LiO-t-Bu and LiO-t-Am/CsF/18-crown-6 (t-Am = CEtMe2) under a CO2 atmosphere to afford a variety of polyfunctionalized aromat

Acyl radicals have been generated from α-keto acids using inexpensive and commercially available 2-chloro-thioxanthen-9-one as the photoredox catalyst under visible light illumination. These reactive species added to olefins or coupled with aryl halides via a bipyridylstabilized Ni(II) catalyst, enabling easy access to a diverse range of ketones. This reliable, atom-economical, and eco-friendly protocol is compatible with a wide range of functional groups.
Method for preparing aromatic ketone in aqueous phase

Paragraph 0042-0045, (2018/04/26)
The invention discloses a method for preparing aromatic ketone in an aqueous phase, comprising the following steps: enabling aryl formyl potassium formate and aryl potassium fluoborate to generate decarboxylation acylation reaction in water under the actions of a silver catalyst and an oxidizing agent, and performing treatment after reaction is ended to obtain the disclosed aromatic ketone. According to the preparation method, the silver catalyst replaces a noble metal catalyst, water is taken as a solvent, an aromatic ketone product is obtained with relatively high yield, the adopted catalystis low in cost and easy to obtain, reaction conditions are mild, and meanwhile, the product is good in university, and therefore, the method has good application potential.
