Formation of racemic crystals of transition metal complexes by grinding 1 ∶ 1 mixtures of enantiomeric crystals†
Abstract
Grinding a 1 ∶ 1 enantiomeric mixture of chiral transition metal complex crystals and subsequent annealing afforded crystals of a racemic compound by diffusion and rearrangement of component molecules, without melting and without racemization of each enantiomeric species.
