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.
