## Abstract Pyridoxal‐5′‐phosphate amino‐oxy acetate oxime was titrated in water, over the pH range 4–12, and the changes followed using ^13^C NMR. The results were compared to those of analogous Schiff's bases presented in the literature. The chemical shifts and titration curves of the oxime were

## Abstract Following our previous reports on the spectroscopy and photochemistry of methyl ethers of cyclic α‐oxo oximes, we have now studied a number of __o__‐ and __p__‐benzoquinone mono‐oxime __O__‐methyl ethers and, for comparison, some corresponding __o__‐ and __p__‐benzoquinones. The ground‐
Method A. Equimolar amounts of freshly sublimed isoindole Ic, d and N-substituted maleinimide IIa-e were stirred at room temperature in absolute ether (or ethyl acetate), after which the reaction mixture was maintained at the same temperature for several hours. When necessary, the solvent was remove
