Bismuth ( III) nitrate is an inorganic chemical compound of bismuth selected from the group of the nitrates.
Production and representation
Bismuth ( III) nitrate in nitric acid can be obtained by dissolving bismuth or bismuth ( III) oxide. The result is this the pentahydrate.
Properties
Bismuth ( III ) nitrate pentahydrate is a colorless solid which is in the form of rod-shaped triclinic crystals. It changes when heated to from about 60 ° C in various basic bismuth ( III) nitrate, and at higher temperatures in the bismuth ( III) oxide. It is soluble in strong mineral acids, and in glycerin and glacial acetic acid. In water decomposition takes place at basic salts such as bismuth (III ) subnitrate. With metal nitrates to form double salts.
Use
Bismuth ( III) nitrate is an excellent oxidizing agent for a variety of 4-substituted Hantzsch 1,4 - dihydropyridines. It is a convenient reagent for the selective oxidation of sulfides to sulfoxides. It is also used as a catalyst for Michael addition with a high yield of various substrates, including amines, imidazoles and indoles to enones.
