Fission of Activated Carbon-Nitrogen and Carbon-Sulphur Bonds. II. Polarographic Reduction of β-Amino Ketonesesponding alcohol. The influence of structure in the ketones of the type R-COCH.CH.NR.R.R. is discussed. At higher pH-values an elimination reaction occurs. The α,β-unsaturated ketone formed in this reaction is manifested by a separate wave on polarographic curves.
