Anwendungen

Lithium amide is used in the preparation of active pharmaceutical ingredients and antioxidants. It acts as a catalyst for polymers, as nucleophiles and as strong bases. It serves as a reagent in the synthesis of antiinflamatory and preoresolving protectin D1, chemotype dipeptidyl peptidase IV inhibitors and sterically congested triarylamines. It finds application in dyes displaying large stokes shifts. In addition to this, it is used as a reagent for cross-coupling of aryl chlorides and amine.

Bemerkungen

Moisture sensitive. Incompatible with strong oxidizing agents, acids, water and alcohols.
