• Description: Bismuth nitrate is the bismuth salt form of nitrate, usually existing in pentahydrate form. People apply bismuth salt to the skin for hemorrhoids. People use bismuth as an enema for pouchitis. This condition involves inflammation in an artificial rectum created after surgery for ulcerative colitis. Bismuth salts are also added to cosmetics, batteries, paints, and pigment plastics in manufacturing. Bismuth nitrate is used to catalyze various kinds of reactions including chemo-selective synthesis of acylals from aromatic aldehydes, one-pot synthesis of alpha-amino phosphates as well as pharmaceutically functionalized piperidine derivatives, protection of carbonyl compounds and various kinds of Michel reactions. It is also an excellent oxidant for a variety of 4-substituted Hantzsch 1, 4-dihydropyridines.It is a convenient reagent for selective oxidation of sufides to sulfoxides.
• Uses: Bismuth(III) nitrate pentahydrate is a non-toxic, inexpensive, easy to handle and air insensitive reagent, commonly used in organic synthesis with a wide range of applications. Bismuth(III) nitrate pentahydrate is a convenient and selective reagent for conversion of thiocarbonyls to their carbonyl compounds. Bismuth(III) nitrate pentahydrate and air as a cocatalyst is claimed to be a superior reagent for the oxidative deprotection of dithioacetals. An excellent oxidant for a variety of 4-substituted Hantzsch 1,4-dihydropyridines.1 Convenient reagent for selective oxidation of sufides to sulfoxides.2 Bismuth Nitrate Pentahydrate acts as a precursor in the prepoaration of photocatalysts. Luminous paints, preparation of bismuth saltsBismuth(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.

Deprotection of semicarbazones using bismuth(III)nitrate pentahydrate supported onto silica gel

10.1080/10426500307776

Shahnaz Khaleghi, Majid M. Heravi, and Lida Fotouhi present an efficient method for the deprotection of semicarbazones to regenerate carbonyl compounds using bismuth(III)nitrate pentahydrate supported on silica gel. The study highlights the environmental and practical advantages of this method, which is relatively nontoxic, easy to handle, and inexpensive. The authors prepared the supported reagent by mixing bismuth nitrate pentahydrate with silica gel and found that it significantly improved the yield of deprotected products compared to using bismuth nitrate alone. The deprotection process was carried out in acetone, and the results showed high yields for a variety of aldehydes and ketones, with no over-oxidation to carboxylic acids observed. The method is particularly notable for its simplicity, mild reaction conditions, and the ease of product isolation, making it a promising approach for the deprotection of semicarbazones in green chemistry.
