Diethyl phosphite, known scientifically as diethyl phosphonate and identified by CAS number 762-04-9, is a colorless liquid organophosphorus compound that serves as a vital intermediate in organic synthesis. Its unique chemical structure and reactivity make it indispensable for a multitude of industrial applications, ranging from catalysis to the production of essential materials. As a leading manufacturer and supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-purity Diethyl phosphite to researchers and industrial clients globally.

The chemical properties of Diethyl phosphite are central to its utility. It exists predominantly in its phosphonate form, (C2H5O)2P(O)H, featuring a reactive P-H bond. This bond is susceptible to deprotonation, enabling crucial reactions such as P-alkylation via the Michaelis-Becker reaction, where it reacts with alkyl halides in the presence of a strong base to form new carbon-phosphorus bonds. Furthermore, Diethyl phosphite readily participates in hydrophosphonylation reactions, where it adds across unsaturated functional groups like aldehydes and imines, forming alpha-hydroxyalkylphosphonates and aminophosphonates, respectively. These reactions are foundational for synthesizing complex organophosphorus molecules.

The versatility of Diethyl phosphite extends to its role in preparing advanced catalysts. It is used in conjunction with nickel chloride to form a highly efficient catalytic system capable of mediating cross-coupling reactions. This application is crucial for industries requiring precise synthesis of complex organic compounds. Researchers looking to buy Diethyl phosphite for catalytic applications can rely on NINGBO INNO PHARMCHEM CO.,LTD. for consistent quality and supply.
