Abstract

Over a period of several years, Japp and his students investigated the properties of certain cyclopentenolones which they termed anhydroacetonebenzils, from the method of preparation. [...] In attempting to ascertain the structure of these substances, dry hydrogen chloride was employed as a reagent; it brought about the replacement of a hydroxyl group by a chlorine atom (1). Japp was unable to determine the nature of this chlorinated derivative from the evidenceat hand. While studying the reactions of cyclopentenolones with various inorganic halogen compounds in this laboratory, Spanagel (2) prepared a chloride isomeric with Japp' s, and found that it was easily converted into the latter by the action of dry hydrogen chloride. Thus it became necessary to assign structures to both compounds.[...]
