Focusing on the Elements- Heavy Hydrogen


Kentaro Sato

Isotope with Its Own Symbol

Discovering and naming a new element are one of scientists’ biggest dreams. The name of an element that you coined would be used for generations to come, so it might be a greater honor than receiving a Nobel Prize. In the history of chemical elements, which we know a few more than a hundred today, there have been many disputes and confusions over claiming that honor. In fact, the number of the “phantom elements” – elements that were given a name once but removed from the periodic table after their identities were proven false - is said to equal that of the “real” elements.

Research Article

Copper-catalyzed Direct Amidation of Heterocycles with N-Fluorobenzenesulfonimide

  Pan et al. have reported the copper-catalyzed direct amidation of heterocycles with N-fluorobenzenesulfonimide (NFSI). According to their results, various heteroarenes such as thiophenes, furans, and pyrroles are converted into the α-amidated heterocycle derivatives in high yields by using NFSI as a nitrogen source and CuI as a catalyst. This reaction presumably proceeds via C—H bond activation. It is expected to be used as a novel synthetic method of valuable amidated heterocycles through a direct C—N bond-coupling process.

Aldehyde Dehydrogenase Inhibitor for Anti-Alcoholism Research

B0479
Disulfiram (other name: tetraethylthiuram disulfide), developed in the 19th century,1) has been used as an organic accelerator of rubber vulcanization.2,3) There are some applications using dislfiram for an additive of living radical polymerization,4,5) a Ca2+-ATPase activator,6) a V-ATPase inhibitor7) and so on.
It was revealed by E. Jacobsen et al. in 1948 that dislfiram absorbed into the body inhibits aldehyde dehydrogenase during the ethanol metabolism, and provokes acute symptoms because of the accumulation of acetaldehyde in the body.8) So disfiram has a deterrent effect of alcoholism.9)
