Sodium N,N-diethyldithiocarbamate reacts smoothly with methylene chloride (even in the presence of various transition metal ions) to give the dithiocarbamate ester Et2NC(S)SCH2S(S)CNEt2 in very high yield. With chloroform and acetonitrile, proton abstraction occurs followed by partial decomposition of the N,N-diethyldithiocarbamic acid so formed to give diethylammonium N,N-diethyldithiocarbamate.

It has been known for a long time that electron irradiation induces damage in maximal valence transition metal oxides such as TiO2, V2O5, and WO3, of which transition metal ions have an empty d-shell. This type of damage is excited by electronic transition and can be explained by the Knoteck-Feibelman mechanism (K-F mechanism). Although the K-F mechanism predicts that no damage should occur in transition metal oxides of which the transition metal ions have a partially filled d-shell, namely submaximal valence transition metal oxides, our recent study on ReO3 shows that submaximal valence transition metal oxides undergo damage during electron irradiation.ReO3 has a nearly cubic structure and contains a single unit in its cell: a = 3.73 Å, and α = 89°34'. TEM specimens were prepared by depositing dry powders onto a holey carbon film supported on a copper grid. Specimens were examined in Hitachi H-9000 and UHV H-9000 electron microscopes both operated at 300 keV accelerating voltage. The electron beam flux was maintained at about 10 A/cm2 during the observation.
