Paragraph 0037-0039, (2020/05/02)
The invention discloses a synthesis method of an aromatic amide compound, and belongs to the technical field of chemical synthesis. The synthesis method comprises the following steps: reacting an aldehyde compound, an O-benzoyl hydroxylamine compound and peroxide in an atmosphere for 6-10 h; and sequentially filtering, washing, drying and carrying out column chromatography separation and purification on the reaction solution after the reaction is finished to obtain the aromatic amide product. The method is direct, simple and efficient, the substrate universality is good, and the obtained aromatic amide compound has great applications in the fields of medicines, pesticides and high polymer materials.

Enabled by merging iridium photoredox catalysis and palladium catalysis, α-oxocarboxylate salts can be decarboxylatively coupled with aryl halides to generate aromatic ketones and amides at room temperature. DFT calculations suggest that this reaction proceeds through a Pd0-PdII-PdIII pathway, in which the PdIII intermediate is responsible for reoxidizing IrII to complete the IrIII-IrIII-IrII photoredox cycle. Like a mergin': Enabled by merging iridium photoredox catalysis and palladium catalysis, palladium-catalyzed decarboxylative coupling of α-oxocarboxylates with aryl halides can proceed at room temperature. DFT calculations suggest that a Pd0-PdII-PdIII catalytic cycle is merged with an IrIII-IrIII-IrII photoredox cycle, in which PdIII is responsible for oxidizing IrII to complete the photoredox cycle.
