应用
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.
Reacts with halotriazines to produce conductive, anisotropic carbon-nitrogen materials.
