Bismuth reactions
Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery-whit… WebJan 7, 2024 · Bismuth-catalyzed transfer hydrogenation of azoarenes and nitroarenes to diarylhydrazines and N -arylhydroxylamines, respectively, with ammonia borane. Another example of the low-valent Bi (I)/Bi (III) redox platform can be found in the catalytic activation of nitrous oxide (N 2 O) ( Figure 7 A).
