Abstract
On June 1, 1965, R. B. Woodward and Roald Hoffmann published their third communication in the Journal of the American Chemical Society in which they applied orbital symmetry control to explain the mechanism of a wide variety of valence isomerizations that they termed "sigmatropic reactions." This publication reveals the research trajectory taken by Hoffmann from which this portion of the no-mechanism problem was solved. Hoffmann used five different quantum chemical tools, all based on either extended Hückel theoretical calculations or frontier molecular orbital theory, in his research. Hoffmann's laboratory notebooks and his three draft manuscripts along with Woodward's four subsequent drafts have survived the past 59 years and provide an excellent window into the thinking and manuscript-writing processes used by these Nobel laureates in February-April 1965.
期刊介绍：
The Chemical Record (TCR) is a "highlights" journal publishing timely and critical overviews of new developments at the cutting edge of chemistry of interest to a wide audience of chemists (2013 journal impact factor: 5.577). The scope of published reviews includes all areas related to physical chemistry, analytical chemistry, inorganic chemistry, organic chemistry, polymer chemistry, materials chemistry, bioorganic chemistry, biochemistry, biotechnology and medicinal chemistry as well as interdisciplinary fields.
TCR provides carefully selected highlight papers by leading researchers that introduce the author''s own experimental and theoretical results in a framework designed to establish perspectives with earlier and contemporary work and provide a critical review of the present state of the subject. The articles are intended to present concise evaluations of current trends in chemistry research to help chemists gain useful insights into fields outside their specialization and provide experts with summaries of recent key developments.
