Radiolysis of Cyclooctane with γ-Rays and Helium Ions

Iodine scavenging techniques have been used to examine the role of the cyclooctyl radical in the radiolysis of cyclooctane with γ-rays and with 5-20-MeV helium ions.In γ-radiolysis about 70percent of the total yield of 6.6 cyclooctyl radicals/100 eV are scavenged with E-4 M iodine, which agrees well with other studies on cycloalkanes that show most of the radicals produced in these systems react in the bulk medium at times longer than 1 μs.However, it is found that 2.5 radicals/100 eV (38percent) are produced by H atom precursors as copmpared to a value of 1.5 cyclohexyl radicals/100 eV (25percent) in cyclohexane.With 10-MeV helium ions (average LET of 106 eV/nm), only 8percent of the cyclooctyl radicals survive longer than a few microseconds due to the increased initial radical concentration in the helium ion track.The yield of the cross-bridged product bicyclooctane (pentalane) was found to be independent of iodine concentration up to 0.03 M with both types of radiation.However, the pentalane yield found with 10-MeV helium ions was only one-third of that found in γ-radiolysis.The most likely reason for this result is the decreased yield of singlet-state formation due to the enhanced probability of cross combination reactions of electron-cation pairs in the high-density region of the helium ion track.

A mild method for the replacement of a hydroxyl group by halogen. 1. Scope and chemoselectivity

α-Chloro-, bromo- and iodoenamines, which are readily prepared from the corresponding isobutyramides have been found to be excellent reagents for the transformation of a wide variety of alcohols or carboxylic acids into the corresponding halides. Yields are high and conditions are very mild thus allowing for the presence of sensitive functional groups. The reagents can be easily tuned allowing therefore the selective monohalogenation of polyhydroxylated molecules. The scope and chemoselectivity of the reactions have been studied and reaction mechanisms have been proposed.
