Woodward-Hoffmann Rules Much of what we have said about the electronic factors controlling pericyclic reaction was formulated in the mid 1960's by the American chemists R. Owing to ring strain in cyclobutene, this reaction gives 1,3-butadiene under thermal conditions, whereas the photochemical reaction can be tuned to drive the reaction in either direction. In a previous section we became familiar with the terminology of cycloadditions and the selection rules for 'symmetry allowed' and 'symmetry forbidden' reactions, based on the properties of FMOs Despite the large number of papers devoted to UV-promoted cyclization of 1,3,5-hexatriene derivatives, the photochemical behavior of aza-analogs has been studied to a much lesser extent.
