Applicazioni

Bismuth(III) nitrate pentahydrate is an oxidant for a variety of 4-substituted Hantzsch 1,4-dihydropyridines. It also serves as a reagent for selective oxidation of sufides to sulfoxides. Further, it is involved in the preparation of Dragendorff reagent and used as a TLC stain. It is also used to prepare other bismuth compounds.

Note

Hygroscopic. Moisture sensitive. Incompatible with strong acids, strong reducing agents, strong oxidizing agents, powdered metals and organic materials.

Letteratura

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. Commun., 31, 2691 (2001). Reagent for deprotection of oximes: Synthesis, 1010 (2001), and hydrazones: Synth. Commun., 32, 1917 (2001). Thioamides and thioureas are readily converted to their oxo-analogs: Tetrahedron Lett., 44, 591 (2003).
