13716-45-5 - Introduction

Diethylene TRIMETHYLSILYL PHOSPHITE (diethylene TRIMETHYLSILYL PHOSPHITE) is an organic phosphorus compound with the chemical formula [(CH3)3Si]O(PEt2), which is colorless liquid in appearance. The following is a description of the properties, uses, preparation and safety information of the compound:

Nature:
-Appearance: colorless liquid
-Solubility: Soluble in many organic solvents, such as ethers, alcohols and alkanes.
-Stability: DIETHYL TRIMETHYLSILYL PHOSPHITE is relatively stable at room temperature, but will be affected by strong oxidants.

Use:
-As a reagent in Organic Synthesis: DIETHYL TRIMETHYLSILYL PHOSPHITE is commonly used in organic synthesis reactions, such as participating in phosphating reactions and reduction reactions as a phosphorus source.
-As a stabilizer: Due to its good stability to air and water, DIETHYL TRIMETHYLSILYL PHOSPHITE can be used as a stabilizer in organic synthesis to protect sensitive groups from oxidants or moisture.

Method:
DIETHYL TRIMETHYLSILYL PHOSPHITE is usually prepared by the following steps:
1. Reacting triethylsilyl dimethyl sulfate with Port reagent to generate diethyltrimethylsilyl phosphite.
2. The obtained phosphite is reacted with alcohol and hydrogenated to dissociate into the corresponding phosphite.

Safety Information:
The safety of diethyltrimethylsilyl PHOSPHITE still lacks a large amount of research data. However, it is worth noting that the use of chemicals should follow the relevant safety procedures. It should be stored in a closed container, away from fire sources and flammable materials. When using, attention should be paid to avoid contact with skin, eyes, clothing, etc., and should be operated under ventilated conditions. If skin contact occurs, rinse off immediately with water. If necessary, the chemical should be used under the guidance of a safety expert.
