trimethyl-[(trimethylsilylimino-λ4-sulfanylidene)amino]silane - Introduction
Bis(trimethylsilyl)sulfur diimide (TMSI for short) is an organic silicon compound with the chemical formula [(CH3)3Si]2S2, which is a colorless to yellow liquid. The following is an introduction to the nature, use, formulation and safety information of TMSI:
Nature:
1. TMSI is an organosilicon reagent with strong electron affinity and oxidation.
2. It is liquid at room temperature and has a stimulating smell.
3. TMSI can react with many organic compounds, including olefins, ethers, amines and ketones.
4. It is soluble in organic solvents, such as ether or chlorinated hydrocarbons.
Use:
1. TMSI is used as an oxidation reagent in organic synthesis, which can convert thiols into corresponding alkenes and other functional compounds.
2. It can also be used to oxidize aldehydes and ketones to generate the corresponding acids or anhydrides.
3. TMSI can also be used for dehydrogenation, dehydration and condensation reactions.
Method:
TMSI can be obtained by reacting chloromethyltrimethylsilane (Cl3SiCH3) with sodium sulfide (Na2S) or potassium sulfide (K2S).
Safety Information:
1. TMSI has a strong irritation, contact with skin or eyes may cause irritation.
2. When operating and handling TMSI, it is necessary to wear appropriate safety protective equipment, such as safety glasses, gloves and protective clothing.
3. Avoid contact with the fire source, so as not to cause a fire.
4. When using or storing TMSI, ensure good ventilation and avoid inhaling its vapors.
5. TMSI should be kept away from oxidants and combustibles, stored in a sealed container, and stored in a cool and dry place.
