Paragraph 0016, (2016/10/10)
The invention discloses a method for preparing a 2-phosphonic acid ester base-1, 3-dicarbonyl derivative. A 1, 3-dicarbonyl derivative and trialkyl phosphite ester are used as starting materials, and a great variety of raw materials are easy to obtain. Varied types of products are obtained through the method, can be directly used, and can also be used for other further reactions. In addition, the reaction is performed in air, the condition is mild, the reaction time is short, the target product yield is high, pollution is small, the reaction operation and aftertreatment process is simple, and the method is suitable for industrial production.

By the CuII-catalyzed decomposition of 2-diazo-1,3-diphenyl-1,3-propanedione in dimethyl hydrogen phosphite dimethyl (dibenzoylmethyl)phosphonate is obtained.By means of IR and PMR spectroscopy it was shown that in the crystalline state the phsphonate exists in the diketo form, but in CDCl3 solution it is an equilibrium mixture of keto and ionized forms.
