Book excerpt: Deuterium: Discovery and Applications in Organic Chemistry provides a well-illustrated overview of the discovery of 2H or heavy hydrogen, the stable hydrogen isotope with both a proton and a neutron in its nucleus. The work introduces the isotope, its discovery, physical properties, nomenclature, and common compounds, also exploring its application in organic chemistry through classic and recent examples from literature. Finally, the book devotes one chapter to Deuterium in medicinal chemistry and the biological effects of Deuterium Oxide, better known as D2O. Provides unique coverage not found elsewhere that is presented in an accessible, dedicated short work Contains practical information and examples on the use of Deuterium (D or 2H, Heavy Hydrogen) in organic synthesis Presents a detailed description of Deuterium’s discovery and applications in the pharmaceutical industry

Book excerpt: In 1931 Vrey, Brickwedde, and Murphy discovered the hydrogen isotope deuterium. The isotopic enrichment was found to arise from the fact that the electrolysis oflight water is faster than of heavy water [1,2]. This success showed that although different isotopes of an element behave identically from a chemical standpoint the different isotopic masses nevertheless lead to both isotope effects on equilibrium as well as on rate constants of chemical reactions. Soon, ratios of equilibrium constants of isotopic reactions were called "equilibrium isotope effects" (EIE), ratios of isotopic rate constants "kinetic isotope effects" (KIE). Isotope effects have been found to be especially large for those elements which are directly involved in bond breaking and bond formation during the reaction studied [3]. Such effects are, therefore, referred to as "primary". Isotopic substitution in atomic sites which maintain all chemical bonds with their neighbors during the reaction of interest leads then only to smaller "secondary" isotope effects. Because of the unique mass relation between the different hydrogen isotopes hydrogen/deuterium isotope effects are particularly large and have attracted most attention. The largest contributions to these effects arise from changes in the vibrational frequencies of the reactants. The theory of equilibrium isotope effects has been founded by Vrey [4] and Bigeleisen [5,6] and has widely been accepted [3].
