, p. 11072 - 11079 (2020)
The straightforward synthesis of N,N-disubstituted formamides using a combination of 1,1,1,3,3,3-hexafluoroispropanol (HFIP) and H2O2 is described. The unique features of HFIP allowed the utilization of a green oxidant such as H2O2, and the products, arising from an oxidation-rearrangement sequence, were obtained in good to high yields under smooth reaction conditions.

Paragraph 0044-0045, (2021/06/06)
The invention relates to the technical field of organic synthesis, in particular to a method for preparing amide compounds through photocatalysis of organic amine. The preparation method comprises the following steps: mixing tetrahalomethane with a solvent, sequentially adding an amine compound, a catalyst and organic carboxylic acid, performing stirring and reacting under an oxygen-containing atmosphere and an illumination condition, and performing separating and purifying to obtain the amide compound with a structure shown in formulas V-VII. According to the method, the reaction is carried out in the air atmosphere under the illumination condition at room temperature and normal pressure, the reaction condition is mild, the raw material source is wide, the cost is low, the byproduct generated after the reaction is the halogen simple substance, the added value is high, a large amount of waste is avoided, and the method has higher atom economy and environmental friendliness and is beneficial to large-scale production.

A novel heterogeneous copper catalyst has been developed by supporting copper nanoparticles on activated charcoal via in situ reducing copper(II) with aqueous hydrazine as reductant. The characterization of Cu/C catalyst showed that the Cu0 nano-particles were formed on the surface of charcoal. This catalyst displayed good catalytic activities toward the N-arylation of primary amides and lactams with aryl iodides.
