General description

The product is 25 wt.% solution of sodium methoxide in methanol. 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 (Dimethylformamide) to afford arenes.


A novel high-spin hexanuclear Mn(III) cluster, [NaMn6(OMe)12(dbm)6]+, was synthesized via MnCl2 oxidation with simultaneous NaOMe promoted aggregation. This cluster has an unprecedented cyclic structure and 24 unpaired electrons in its ground state.

Sodium methoxide solution has been used in the synthesis of NO-containing nanoparticles (SNO-NP).
