Woodward-Hoffmann rules

The Woodward-Hoffmann rules are a set of four rules that predict the stereochemical outcome of pericyclic reactions. They were developed by Robert Burns Woodward and Roald Hoffmann in 1965, and they have since become one of the most important tools in organic chemistry.

Rule 1: The total number of (4n + 2) electrons in the reactants and products must be the same.
Rule 2: The symmetry of the highest occupied molecular orbital (HOMO) of the reactants must match the symmetry of the lowest unoccupied molecular orbital (LUMO) of the products.
Rule 3: The reaction must take place in a concerted manner.
Rule 4: The reaction must take place with conservation of orbital symmetry.

The Woodward-Hoffmann rules have been used to predict the stereochemical outcome of a wide variety of pericyclic reactions, including cycloadditions, electrocyclic reactions, and sigmatropic rearrangements. They have also been used to design new synthetic methods for the synthesis of complex organic molecules.
