Synthesis of alpha-diketones
Alpha-diketones, such as 1-phenyl-1,2-propanedione and 1-propyl-1,2-butanedione, are prepared by reacting an acylmethyl ester of a carboxylic acid (e.g., benzoylmethyl acetate or butanoylmethyl propionate) with an aldehyde, such as formaldehyde or acetaldehyde, in the presence of an acid catalyst an...

| Zusammenfassung: | Alpha-diketones, such as 1-phenyl-1,2-propanedione and 1-propyl-1,2-butanedione, are prepared by reacting an acylmethyl ester of a carboxylic acid (e.g., benzoylmethyl acetate or butanoylmethyl propionate) with an aldehyde, such as formaldehyde or acetaldehyde, in the presence of an acid catalyst and water. Such alpha-diketones are also obtained by first refluxing a mixture of an alpha-haloketone and a carboxyl anion source and then reacting the mixture with an aldehyde in the presence of an acid catalyst and water. |
