1-(TRIMETHYLSILYL)-1-HEPTYNE - Introduction
1-Heptynyltrimethylsilane(1-Heptyne trimethylsilyl) is an organosilicon compound with the molecular formula C10H20Si and a molecular weight of 172.36. It is a colorless liquid with a special smell.
1-Heptynyltrimethylsilane is often used as a reagent in organic synthesis in chemical reactions. It can be used as a protecting group in organic synthesis, and can protect the active hydrogen in carbonyl compounds to prevent unnecessary reactions. In addition, it can also be used for catalyst modification and catalytic reactions in organic synthesis.
The method for preparing 1-Heptynyltrimethylsilane is usually obtained by reacting trimethylchlorosilane with 1-heptyne in the presence of copper chloride. The reaction conditions are generally room temperature or heating, and an inert solvent such as tetrahydrofuran (THF) or dimethylformamide (DMF) is used to dissolve the reactants.
Regarding safety information, 1-Heptynyltrimethylsilane is a flammable liquid and needs to be operated in a well-ventilated place and away from open flames and ignition sources. Appropriate protective equipment such as chemical goggles, protective gloves and laboratory coats should be worn during handling. After contact with skin or eyes, rinse immediately with plenty of water and seek medical advice.
