Applications of 1777-03-3
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Used as an alkynyl protecting group for selective carbon–carbon bond formation | Deprotonated under basic conditions (e.g., n-BuLi), then added to aldehydes/ketones, or employed in Sonogashira coupling; the TES group is subsequently removed under mild conditions using fluoride (e.g., TBAF) |
| Pharmaceutical R&D | Used in the synthesis of bioactive molecules and drug intermediates containing alkyne moieties | Serves as a key building block to introduce terminal alkynes, enabling conjugation of targeting groups or fluorescent labels via Cu(I)-catalyzed azide–alkyne cycloaddition (CuAAC) |
| Materials Science | Used to prepare conjugated polymers and organic semiconductor materials | Employed in Stille, Suzuki, or Sonogashira cross-coupling reactions to construct π-conjugated backbones for OLED and OFET devices |
| Agrochemical Chemistry | Used to synthesize novel agrochemically active compounds containing silyl-alkyne structures | Functions as a functionalized intermediate to introduce silyl groups, thereby modulating lipophilicity and metabolic stability, and participates in multi-step functional group transformations |
