产品说明

应用

Reacts with halotriazines to produce conductive, anisotropic carbon-nitrogen materials.
Lithium (trimethylsilyl)acetylide can be used as a reagent:

  • In the transmetalation and nucleophilic displacement reactions.
  • To prepare propargylic alcohol derivatives by reacting with aldehydes and ketones.
  • To synthesize α,βynones by treating with Weinreb amide or with isoxazolidide.
  • Along with Grignard reagent to convert γ- and δ-thiolactams to thioiminium salts, which are employed as key intermediates to produce disubstituted pyrrolidines.

包装
