• Useful, easily handled oxidizing and nitrating agent in organic synthesis. Montmorillonite KSF acidic clay impregnated with bismuth nitrate was found to be an excellent reagent for high-yield aromatic nitration: Tetrahedron Lett., 41, 8017 (2000). Phenols can be nitrated with the salt itself in acetone, or without solvent: J. Org. Chem., 70, 9071 (2005). In the presence of montmorillonite, alcohols can be oxidized to carbonyl compounds: Synth.
