The invention discloses a phosphonic-containing carboxylic acid compound and a preparation method thereof. The preparation method comprises the following steps: mixing and dissolving a reaction substrate, a phosphine oxide compound and alkali, adding a photocatalyst in a carbon dioxide atmosphere, and then carrying out an illumination reaction at 10-60 ℃ for 2-24 hours at 1-100W. The method has the advantages of mild reaction conditions, wide selectivity of reaction substrates, amplification to gram-scale and basically unaffected yield. |
