Preparation, reactions, and physical properties of organobismuth compounds

The Chemistry of Organo-Arsenic, Antimony and Bismuth Compounds: An Overview

“…The organometallic chemistry of pentavalent arsenic [63], antimony [64] and bismuth [65] compounds has been reviewed. The metal atom in these compounds acquires usually pentacoordination with a trigonal bipyramidal configuration, the exception being Ph 5 Sb which has a square pyramidal configuration [10].…”

First synthesis of the bismole‐containing conjugated polymer

“…Its toxicity is much lower than that of other heavy elements around bismuth in the periodic table, for example, arsenic, antimony, tin, and lead. The properties of trivalent organobismuth compounds are fairly different from those of trivalent organophosphorus compounds 25–27. The lone pair of electrons on the bismuth atom of trivalent organobismuth compounds possesses s ‐character, weak nucleophilicity, and weak basicity, while that on the phosphorus atom has strong nucleophilicity and strong basicity.…”

“…On the other hand, bismuth is an element of the 15th group and the 6th period in the periodic table, and the organobismuth‐mediated reaction offers a potentially important methodology for synthetic organic chemistry 25–27. Bismuth is the heaviest known element that exists stably on earth 28.…”

Synthese und Einkristallröntgenstrukturanalyse von Bromdi(isopropenyl)bismutan

“…Ausnahmen bilden Verbindungen, die sterisch anspruchsvolle Liganden enthalten und durch intramolekulare Koordination stabilisiert sind [14]. α-Alkenylliganden wirken mo È glicherweise schwach stabilisierend auf die Bi±C rBindung [15], analog zu den stabileren Bismutanen mit aromatischen Liganden [16].…”
