Product Name:(4-Chlorophenylethynyl)trimethylsilane
English Name:(4-Chlorophenylethynyl)trimethylsilane
CAS No.:78704-49-1
Aliases:1-Chloro-4-((trimethylsilyl)ethynyl)benzene, 2-(4-Chlorophenyl)-1-(trimethylsilyl)acetylene
Molecular Formula:C11H13ClSi
Physical Properties:Colorless to pale yellow transparent liquid at room temperature. Soluble in chloroform, dichloromethane, ethyl acetate, toluene and other organic solvents; insoluble in water. Exhibits typical alkynylsilane reactivity and can be desilylated under basic conditions to generate the terminal alkyne; serves as a versatile building block for conjugated alkynes and polyaryl-substituted alkenes.
Uses:Used in organic synthesis to introduce the 4-chlorophenylethynyl moiety. Serves as a substrate for Sonogashira coupling, Glaser coupling and related reactions. Employed in the preparation of bioactive molecules, optoelectronic materials and functional polymers.
Technical Specifications:
Purity: ≥97%
Molecular weight: 208.76
Boiling point: approximately 230°C (estimated at atmospheric pressure)
Density: approximately 1.04 g/mL at 25°C
Storage conditions: keep sealed, protected from light, in a cool dry place; inert gas protection recommended
