The 2D representations, IUPAC names and stereochemical assignments were created using ChemDraw 18.2 using 3D coordinates provided by Gaussview. The molecules above include examples of point chirality, axial chirality, helical chirality and planar chirality. These optional footnotes relate to more advanced concepts that will be encountered in future lectures. aAsymmetrically substituted ferrocenes exhibit Planar Chirality, despite having no stereogenic atom centre. bNot configurationally stable because of fast (at room temperatures) atropisomerism (rotation about cyclic single bonds). cOctahedral molecules have λ/δ ligand twists and the complexes Λ/Δ chiral configurations. For more information and examples, see here. eConfigurationally stable (planar chirality) because of slow (at room temperatures) atropisomerism.
