Its chemical formula is C8H17O5P. It has certain physical and chemical properties. In terms of appearance, it is usually a clear liquid. It has a specific boiling point, melting point, and density. The boiling point is around 100 - 102°C at 0.2 mmHg. This information is crucial for storage and handling, as well as for its use in various chemical reactions.
Triethyl phosphonoacetate is widely used in organic synthesis. One of its main applications is in the Horner - Wadsworth - Emmons reaction. In this reaction, it reacts with aldehydes or ketones to form α,β - unsaturated esters. This is a very important reaction in the synthesis of complex organic molecules, such as natural products and pharmaceuticals.
It can also be used in the preparation of various phosphonate - containing compounds. These compounds have applications in areas such as agrochemicals, where they can act as herbicides or insecticides. In the field of materials science, phosphonate - based compounds can be used as additives to improve the properties of polymers, such as flame - retardancy and adhesion.
When using Triethyl phosphonoacetate, appropriate safety precautions should be taken. It is recommended to wear protective clothing, gloves, and safety glasses to avoid direct contact with the skin, eyes, and respiratory tract. In a laboratory or industrial setting, it should be used in a well - ventilated area or under a fume hood.
For reaction purposes, the appropriate reaction conditions need to be determined according to the specific reaction type. For example, in the Horner - Wadsworth - Emmons reaction, the reaction usually requires the presence of a base. The reaction temperature, reaction time, and molar ratio of reactants are also important factors that affect the reaction yield. Generally, the reaction temperature can range from room temperature to reflux temperature depending on the specific reaction system.
In a pharmaceutical research project, a research team aimed to synthesize a novel anti - cancer drug. Triethyl phosphonoacetate was used as a key intermediate in the synthesis. The Horner - Wadsworth - Emmons reaction was employed to form an α,β - unsaturated ester, which was then further modified through a series of reactions.
The research team first optimized the reaction conditions. They tested different bases and found that sodium hydride gave the best yield. They also adjusted the molar ratio of Triethyl phosphonoacetate to the aldehyde and found that a 1.2:1 ratio gave a satisfactory result. By carefully controlling the reaction temperature and time, they were able to obtain the desired product with a high purity of over 95%. This case study shows the importance of Triethyl phosphonoacetate in pharmaceutical synthesis and the significance of optimizing reaction conditions.
