EPR of hydrogen in lithium oxide

open access: yesJournal of Physics: Condensed Matter, 1991
The EPR spectrum of interstitial H0 has been observed in X-irradiated Li2O. Transferred hyperfine structure for 7Li nuclei shows that at 4 KH0 is strongly coupled to four equivalent 7Li neighbours, whereas at 300 K it is coupled to eight 7Li neighbours.

On the Nature of the Oxidative Heterocoupling of Lithium Enolates [PDF]

open access: yesJournal of the American Chemical Society, 2011
The coupling of enolates through single-electron oxidation is one of the most direct routes for generating 1,4-dicarbonyls. Recent work on the intermolecular heterocoupling of equimolar amounts of two different enolates through single-electron oxidation has shown that synthetically useful yields beyond those predicted by statistics can be obtained.
