Bailar twist

The Bailar twist is a mechanism proposed for the racemization of octahedral complexes containing three bidentate chelate rings. Such complexes typically adopt an octahedral molecular geometry and are thus chiral. One pathway by which these compounds can racemize is via the formation of a trigonal prismatic intermediate with D3h point group symmetry. An alternative pathway is called the Ray-Dutt twist. This pathway is called the Bailar twist in honor of John C. Bailar, Jr., an inorganic chemist who investigated this process.
