Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the field of application catalytic synthesis of organic phosphonate compounds, in particular to a preparation method for preparing organic phosphonate derivatives by efficiently esterifying P (O) -OH-containing compounds and alcohol.
[ background of the invention ]
The organic phosphonate compounds are important organic compounds in organic synthesis, and have good catalytic activity, optical activity and biological activity, so that the organic phosphonate compounds have wide application in the aspects of biological, medical and optical active materials, asymmetric catalytic synthesis and the like. Phosphorus and organic phosphorus compounds are known to be important substrates in life, such as ADP, ATP, RNA, organic phospholipid bilayers and the like in human bodies. However, it is difficult to find a natural organic phosphonate compound in nature, and most of phosphorus exists in nature in the form of inorganic salt, and most of the organic phosphonate compounds known at present are synthesized by chemical methods.
In recent years, with the continuous expansion of the application field of organic phosphonate (especially as organic ligand), the market demand is also increasing, and the development of new synthesis technology of the compounds is also receiving more and more attention. The synthesis method of the organic phosphonate compounds reported in the literature at present mainly comprises the following steps: (1) Atherton-Todd reaction: catalyzing a P (O) -H bond compound to perform cross coupling reaction with a nucleophilic reagent (alcohol, phenol, amine compound and the like) in the presence of reagents such as carbon tetrachloride, triethylamine and the like; (2) nucleophilic substitution reaction: the compound containing P (O) -H or P (O) -OH reacts with a halogenating agent to prepare a corresponding compound containing P (O) -Cl, and then the compound and a nucleophilic reagent (alcohol, phenol, amine compound and the like) are subjected to cross coupling reaction; (3) arbuzov reaction: the trialkyl phosphite is used as a nucleophilic reagent to react with alkyl halide to prepare the dialkyl alkylphosphonate. (4) And (3) cross-coupling reaction: noble metal catalysts (palladium, silver, copper, nickel) are used for catalyzing the cross coupling reaction of nucleophiles such as P (O) -H and the like and compounds such as R-X/Ar-X and the like. However, the above methods generally employ air-sensitive reagents (p (o) -H compounds, carbon tetrachloride, sulfonyl chloride, etc.), and have the disadvantages of complicated experimental steps, expensive catalyst, difficult recycling, harsh reaction conditions, cross-reactivity of substrates, low yield, and great environmental pollution.
So far, the high-efficiency synthesis of organic phosphonate compounds has the problems of raw material quality, production safety (the compounds such as phosphorus trichloride, phosphorus pentachloride, phosphorus oxychloride and the like have strong corrosiveness) and stability, purity and the like of products, the synthesis technology has great difficulty, only a plurality of companies in the countries of America, Japan and the like are used for production at present, and the current situation of high-end organic phosphonate products in China mainly depends on import.
Aiming at the defects of the existing organic phosphonate ester synthesis process, the industry is focusing on developing a method for efficiently and selectively synthesizing the corresponding organic phosphonate ester compound by using a stable, cheap and easily obtained P (O) -OH-containing compound as a raw material.
