The Aromaticity of Pericyclic Reaction Transition StatesHenry S. Rzepa Presents an approach that combines two fundamental concepts in organic chemistry, chirality and aromaticity, into a simple rule for stating selection rules for pericyclic reactions in terms of achiral Hckel-aromatic and chiral Mbius-aromatic transition states. Rzepa, Henry S. J. Chem. Educ.2007, 84, 1535.
