N.m.r. spectra of Na– and Rb– in solutions of sodium and rubidium in 1,4,7,10- tetraoxacyclododecane (12-crown-4)
Abstract
We report the n.m.r. spectra of sodide (Na–) and rubidide(Rb–) ions in the title solvent; these two-component metal solutions represent a convenient, stable source of high concentrations of alkalide ions in solution.
