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.

An iron-catalyzed deconstruction/hydrogenation reaction of alcohols through C-C bond cleavage is developed through photocatalysis, to produce ketones or aldehydes as the products. Tertiary, secondary, and primary alcohols bearing a wide range of substituents are suitable substrates. Complex natural alcohols can also perform the transformation selectively. A investigation of the mechanism reveals a procedure that involves chlorine radical improved O-H homolysis, with the assistance of 2,4,6-collidine.

In this communication we describe a novel strategy for the formation of valuable diaryl and aryl alkyl ketones from acyl hydrazides. A wide variety of ketones are prepared and the mild reaction conditions allow for the use of a range of functionalities, especially in the synthesis of diaryl ketones.

A new protocol for the direct acylation of aryl bromides with aldehydes is established. It appears to involve palladium-amine cooperative catalysis, affording synthetically important alkyl aryl ketones in moderate to excellent yields in a straightforward manner, and broadening the scope of metal-catalyzed coupling reactions.

(Chemical Equation Presented) The compatibility between [{IrCl(cod)} 2] and ruthenium complex 1 to achieve asymmetric α-alkylative reduction of prochiral ketones with primary alcohols is an essential factor in obtaining optically active alcohols with elongation of the carbon skeleton in good yields with a high enantioselectivity.
Ruthenium-catalyzed coupling of aldimines with arylboronates: New synthetic method for aromatic ketones
Park, Young Jun,Jo, Eun-Ae,Jun, Chul-Ho
, p. 1185 - 1187 (2007/10/03)
Using the chelation strategy, the reaction of aldimines bearing the 3-picolin-2-yl group with various arylboronates in the presence of a ruthenium catalyst furnished the corresponding ketimines in high yields for a short reaction time; the resulting ketimines were readily converted to ketones by hydrolysis.

Palladium-catalyzed intermolecular hydroamination of alkynes: A dramatic rate-enhancement effect of o-aminophenol
Shimada, Tomohiro,Yamamoto, Yoshinori
, p. 12670 - 12671 (2007/10/05)
The hydroamination of alkynes using o-aminophenol proceeds in very high to good yields in the presence of Pd(NO3)2 catalyst. Remarkable rate enhancement with o-aminophenol is presumably due to the chelation effect of the ortho OH group to palladium. Copyright
