G. Mechanisms that can Racemize Λ and Δ Metal Tris Chelates
Non-dissociative Mechanisms: b. The Rây-Dutt Mechanism for GaL3 (L = mda)


Λ-GaL3
Calc C2v TS for the Rây-Dutt


Viewing the Rây-Dutt Mechanism
  2. Compare to Λ
  3. Compare to Δ
Test each isomer before and after one Rây-Dutt:

Δ-GaL3







State whether facial and meridional isomers can, cannot or must be interchanged by a Rây-Dutt Twisting motion
