✦ Synopsis

A remarkably stable hexacoordinate bismuth ate complex (12) with two bidentate ligands was synthesized by the reaction of a pentacoordinate bismuth compound bearing a Bi-Cl bond (7_) with a dilithiated reagent (2_). The complex was stable up to 150 OC and was decomposed by water to afford an alcohol (g) quantitatively.

Hypervalent bismuth compounds are generally of low stability because of the weakness of Bi-C bonds.
