Bismuth reacts with fluorine, F 2, to form the pentafluoride bismuth (V) fluoride. Under controlled conditions, bismuth reacts with the halogens fluorine, F 2, chlorine, Cl 2, bromine, Br 2, and iodine, I 2, forming the respective bismuth (III) trihalides.
Reactions between bismuth trihalides and organoselenium compounds book Bismuth (III) is precipitated by iodide. Excess iodide will dissolve the precipitate. A series of intramolecularly coordinated organochalcogen compounds incorporating the 8-(dimethylamino)naphthyl and 2-[(dimethylamino)methyl]phenyl groups has been synthesized.
All the compounds were synthesized using the ortholithiation methodology. Insertion of elemental selenium into the Li−C bond of RLi (6) (R = 8-(dimethylamino)naphthyl) afforded the lithium areneselenolate Cited by: ) INTRODUCTION The reaction between pyramidon and bismuth iodide was studied by us hetero- metrically1.
More than ten well defined stoechiomctric compounds were obtained. Each of four of them could be used for a precise détermination of either bismuth or by: Reaction of bismuth with acids. Bismuth dissolves in concentrated sulphuric acid, H 2 SO 4, or nitric acid, HNO 3, to form solutions containing Bi(III).
The sulphuric acid reaction produces sulphur(IV) dioxide gas. With hydrochloric acid in the presence of oxygen, bismuth(III) chloride is produced. Reaction of bismuth with the halogens Bismuth reacts with fluorine, F2, to form the pentafluoride bismuth (V) fluoride.
Bismuth reacts under controlled conditions with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2, and iodine, I2, to form the respective trihalides bismuth (III) fluoride, BiF3, bismuth (III) chloride, BiCl3.

Introduction. Organoselenium compounds attracted a continuous interest over the last decades owing to their biological and technical importance.They found valuable applications in organic synthesis, either as catalysts or transfer reagents, in biochemistry, or as precursors for electronic specific behaviour of selenium is better understood by taking into account its Cited by: 3.
Organobismuth chemistry is the chemistry of organometallic compounds containing a carbon to bismuth chemical bond. According to one reviewer, applications are rare even though bismuth and bismuth compounds are the least toxic among the heavy metals and are relatively cheap.

Organoselenium compounds are known to possess antioxidant, anticancer and antibacterial activities. In the present study, 3-[(phenylcarbonyl)selenyl]propanoic acid was synthesized and different. Scientific literature indicates that some of the compounds of bismuth are less toxic to humans via ingestion than other heavy metals (lead, arsenic, antimony, etc.) presumably due to the comparatively low solubility of bismuth ciation: /ˈbɪzməθ/ (BIZ-məth).
Bismuth is a brittle metal, so it is usually mixed with other metals to make it useful It is used in extinguishers, electric fuses, and fire detectors.
Certain bismuth compounds are also manufactured and used as Mass: In the past, the title compounds were prepared mainly by reduction of aryltellurium trihalides, in some cases under drastic reaction conditions 5,9,11,12 (Scheme 11).
