General description
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.
Application
Sodium methoxide may be used as an alkali catalyst for the production of fatty acid methyl esters (biodiesel) from vegetable oils via transesterification.
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).
