N2  - The protonation reactions of the diamine dioxime 4,4,9,9-tetramethyl- 5,8-diazadodecane-2,11-dione dioxime and its O-methyl and bis-O-methyl ethers have been studied at 25°, I 0.10 M NaCl. The (substituted) oxime groups cause a marked reduction in the basicity of the secondary amino groups. log K (potentiometric) and &#916;H (calorimetric) data are interpreted in terms of inductive effects of the oxime group and possible intramolecular hydrogen bonding, N+-H...N(OR)=, pKa for methoxy-amine, NH2OMe, has been determined (4.62±0.01, I 0.10 M NaCl, 25°).        P.m.r. spectra are assigned for &#946;-amino ketoximes having &#945;- methyl and &#945;-methylene groups cis and trans to =N-OR groups. Infrared spectra are reported.
