Entries 1 and 2 in Table 8 are examples of an overall antarafacial 1,3-transposition of a hydroxy group by selenium compounds20,21. Treatment of the alcohols with 2-nitrophenyl seleno-cyanate in the presence of tributylphosphine gave the selenide with inversion of configuration. Oxidation with hydrogen peroxide led to the selenoxide, which rearranged suprafacially to the allylic alcohol.

The ideas of the valence shell configuration, oxidation number, Lewis structure and the shape of Main Group compounds are brought together in discussing a very important group of compounds of the Main Group elements, namely, the oxyacids and their oxyanions (Table 5.1).

The application of MOssbauer spectroscopy to silicate mineralogy has been well described in two papers by Bancroft et al, in which the influences of electronic configuration, oxidation state, and coordination symmetry of the iron cations were correlated firstly with silicates of known structures [212], and latterly with silicates of unknown and complex structures [213]. Most of the data discussed here are taken from these works, but references are given where appropriate to other data available. Silicate minerals of lunar origin are discussed on p. 294.

Boron tribromide has also been used as a haloboration reagent, in particular by Suzuki and CO workers For instance, they reacted it with terminal acetylenes and subsequently converted the monoaddition product to a 1,2-dihalo-1 -alkene. Since the addition proceeds regio- and stereoselectively and the halogenation occurs with retention, the 1,2-dihalo products have the (Z)-configuration. Oxidation of the addition product by 30% hydrogen peroxide in a solution buffered at pH 5 and in the presence of potassium acetate afforded a 2-bromoalkanaE A combination of halo- and hydroboration was applied in a one-pot...

We examine the physical properties, electron configurations, oxidation states, and magnetic properties of the transition metais. 

In conjunction with these efforts, calculations were made to predict the chemical properties of the Superheavies so that likely ores could be chosen for investigation and separation schemes devised. Separation techniques were developed to purify and identify elements with lifetimes as short as a thousandth of a second. Models were developed to predict such aggregate properties as entropies from samples as small as 500 atoms. Ground-state electron configurations, oxidation states, ionization energies, metallic radii, ionic radii, densities, melting points.
