WebA new drug of bismuth with d -polygalacturonic acid, the so-called ‘colloidal bismuth pectin,’ was approved for clinical use in China in the treatment of peptic ulcers and has achieved an effectiveness similar to colloidal bismuth subcitrate. Table 1. The efficacy of first-, second-, and third-line H. pylori eradication therapies Bismuth has few commercial applications, and those applications that use it generally require small quantities relative to other raw materials. In the United States, for example, 733 tonnes of bismuth were consumed in 2016, of which 70% went into chemicals (including pharmaceuticals, pigments, and cosmetics) and 11% into bismuth alloys.
WebA variety of bismuth compounds have been used in organic transformations over the last 10–15 years because of their low toxicities, a wide range of reactivities, and low cost.62 Catalytic quantities of bismuth (III) compounds are effective in promoting the rearrangement of epoxides to carbonyl compounds. WebJan 7, 2024 · In contrast, bismuth offers a unique opportunity for reactivity beyond such canonical redox pair through one-electron Bi (II)/Bi (III) redox processes. As a seminal example of Bi (II) radical intermediates for synthetic use, Yamago reported organobismuthine-mediated radical polymerization reactions in 2007 ( Figure 2 ).
