说明

應用

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.

包裝

The 25 mL Sure/Seal^™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
