The 27Al nuclear magnetic resonance (NMR) spectrum of NaAlO2 solutions of pH 9.5-12.0 is consistent with the presence of the Al(OH)4- anion. Flash photolysis of an aqueous solution of NaAlO2 and K2S2O8 of pH 9.5-12.0 gives rise to a transient species with an absorption maximum at 610 nm (ε{lunate}=75 m2 mol-1). The pKa value and reduction potential of the radical are found to be 10.8 and 1.5 V respectively. The rate constants for the oxidation of several organic compounds have been determined. © 1993.

Carbonate radicals react with aliphatic amines by a dual mechanism, viz. (i) hydrogen abstraction and (ii) electron transfer. The former is more probable with primary amines. Tertiary amines react via electron transfer. Both mechanisms may operate in secondary amines. Cyclic tertiary amines react with different rates and their relative reactivities are explained on the basis of the concept of Hoffmann's 'through bond' interaction. © 1985.
