The names of Robert Burns Woodward (1917–79), U.S. chemist, and Roald Hoffmann (b. 1937), Polish-born U.S. chemist, used attrib. with reference to a series of generalized symmetry selection rules first proposed by them in 1965 which predict whether a particular pericyclic reaction will be allowed under the given conditions.
1968Jrnl. Amer. Chem. Soc. XC. 1920/2 A considerable amount of research has been directed toward exploring the validity and extent of applicability of the ‘Woodward-Hoffman rules’. 1974Gill & Willis Pericyclic Reactions iv. 100 (heading) The general Woodward-Hoffmann rule for pericyclic reactions. 1980M.
