Paragraph 0041-0049; 0061-0065; 0067, (2022/04/16)
The invention provides a preparation method of an aryl ketone compound, and belongs to the technical field of compound synthesis. The method comprises the following steps: under the action of a silver catalyst and water, carrying out reaction on aryl alkyne with a structure as shown in a formula 1 in a solvent at 60-120 DEG C for 12-48 hours, and separating and purifying a product after the reaction is finished, so as to obtain the single aryl ketone compound with a structure as shown in a formula I, the raw materials are easy to obtain, the experimental operation is simple, the yield of the prepared single aryl ketone compound is good, and gram-scale experiments can be carried out.
Palladium-catalysed transfer hydrogenation of aromatic nitro compounds - An unusual chain elongation
Németh, János,Kiss, árpád,Hell, Zoltán
, p. 6094 - 6096 (2013/10/22)
Aromatic nitro compounds are reduced via transfer hydrogenation in the presence of palladium on magnesium-lanthanum mixed oxide support in ethanol yielding the corresponding amines. With several acetophenone derivatives, the reduction was accompanied by c
