Paragraph 0050-0052, (2017/03/08)
The invention discloses method for preparing (E)-2-aryl vinyl phosphonate derivatives. The method comprises the specific following steps of dissolving 1-nitro-2-aryl-vinyl derivatives, a phosphorus reagent, an accelerator manganese acetate and a catalyst copper acetate in a solvent and reacting at 20-100 DEG C to obtain the (E)-2-aryl vinyl phosphonate derivatives. According to the method disclosed by the invention, the 1-nitro-2-aryl-vinyl derivatives are adopted as starting materials, the raw materials are easily available and have multiple varieties; the products obtained by the method disclosed by the invention are multiple and can be directly applied and can be also used for other further reaction; according to the method, the use of precious metal reagents and other additives is avoided; and meanwhile, the synthetic route is short, reaction conditions are mild, the reaction operation and post-treatment process are simple, the yield is high and the method is suitable for scale production.
