Abstract
Methods of forming arenes, including asymmetrical arenes, such as asymmetrical pyrene derivatives. Substituents of starting materials may be selected to direct a photochemical cascade and possibly a 1,2-aryl shift. The methods may include a Mallory cyclization, which is controlled, at least in part, by substituents of the starting materials. Compounds and compositions including asymmetrical arenes.
