Descrizione generale

Sodium methoxide is a sodium alkoxide. Its reaction with unactivated aryl bromides in the presence of copper catalyst under various reaction conditions has been studied. It reacts with aryl halides in the presence of a palladium catalyst in DMF to afford arenes.

Applicazioni

Sodium methoxide has been used in the preparation of 5-(3-azidopropyl) uridine. It may be used in the synthesis of methyl 2-cyano-lup-3-hydroxy-2-en-28-oate (CN-BA), a 2-cyano derivative of betulinic acid (BA).
Sodium methoxide may be used as an alkali catalyst for the production of fatty acid methyl esters (biodiesel) from vegetable oils via transesterification.
