Synthesis, structure and reactivity of complexes containing a transition metal–bismuth bond

摘要: Abstract The transition metal chemistry of bismuth has attracted significant interest since the 1970s. low cost and high abundance bismuth(III) reagents, such as trihalides, makes them ideal starting materials size centre allows three- higher-coordinate complexes to be synthesised, in which atom is linked one or more fragments. ability vary these fragments gives access a plethora available structures, with cyclopentadienylcarbonyl, carbonyl sandwich compounds existence. Significant recent study focused on applications catalysis, where species can act cross-coupling agents carbon–carbon, carbon–nitrogen carbon–oxygen bond forming reactions. Another striking feature variation bonding situations that observed when studying organometallic bismuth. For example, dative covalent interactions have been reported, addition cases dibismuth acting two-, four- six-electron donating ligand. This review aims demonstrate multi-faceted nature provide detailed coverage this topic.
