Research Interests

 

Physical Chemistry.  Prof. Dewald's research interests were in the area reduction rates for both organic and inorganic reactions using dilute metal ammonia solutions as sources of solvated electrons. The reactions are such that their mechanisms have general application in a variety of cathodic electrochemical and dissolved metal processes. He was particularly interested in the role of the metal cation in these reductions.  He also investigated the chemistry of the anions of the alkali metals. Metal anions are expected to be strong bases by virtue of their electron pairs and their chemical behavior should resemble that of the hydride ion. Prof. Dewald found that sodium dissolves in 1,4,7,10 tetraoxacyclodeodecanes, forming stable and highly concentrated blue metal anion solutions. These solutions were key to the chemistry of the alkali metal anions.
