Cas no 787617-56-5 (((4-((4-Methoxyphenyl)ethynyl)phenyl)-ethynyl)trimethylsilane)
((4-((4-Methoxyphenyl)ethynyl)phenyl)-ethynyl)trimethylsilane is an organosilicon compound featuring a conjugated ethynylphenyl backbone with a terminal trimethylsilyl group and a 4-methoxyphenyl substituent. Its extended π-conjugation system makes it valuable in organic synthesis, particularly for cross-coupling reactions such as Sonogashira or Hagihara couplings, where it serves as a versatile building block. The trimethylsilyl group enhances stability and facilitates further functionalization, while the methoxy moiety offers electronic modulation for tailored reactivity. This compound is useful in materials science, especially for constructing molecular wires, optoelectronic materials, or metal-organic frameworks. Its well-defined structure and synthetic flexibility make it a reliable intermediate for advanced research applications.
