Schiff bases. Part III. Amine and ketone exchange reactions with Schiff bases
Journal of the Chemical Society C: Organic, 1968Certain ketimines of the type R12 CN–CHR22 undergo amine exchange when heated with diphenylmethylamine to give the ketimines R12CN–CHPh2, which rearrange to the tautomers R12CH–NCPh2. These undergo a second amine exchange with the production of N-(diphenylmethylene)diphenylmethylamine.

Synthesis of acyclic dinucleating Schiff base-pyridine and schiff base-phosphine ligands
Tetrahedron Letters, 1995Abstract 5-tert-butyl-3-pyridyl-salicyaldehyde and 5-tert-butyl-3-diphenylphosphino-salicyaldehyde have been synthesized from 4-tert-butylphenol in good overall yields. Condensation of the salicyaldehydes with 2,3-diamino-2-3-dimethylbutane afforded the desired dinucleating Schiff base-pyridine and Schiff base-phosphine ligands respectively.

Polymeric Schiff Bases. III. Some Prototype Exchange Reactions of Schiff Bases
Journal of Macromolecular Science: Part A - Chemistry, 1967Abstract The amine moiety in Schiff bases can be exchanged quantitatively by another amine to yield new Schiff bases if the volatility of the replacing amine is lower than the derived amine, thereby allowing the latter to distilled from the reaction mass. This amine exchange was shown to be quantitative also for diamines and di-Schiff bases. Similarly,

Spectroscopy of non-aromatic Schiff bases
Journal of Photochemistry, 1981Abstract The photoelectron and vapour phase UV absorption spectra of a number of non-conjugated and conjugated imines, their oximes and O -methyloximes were determined. The assignment of the bands of lowest frequency is discussed as well as the nature of the primary steps that may occur in the related excited states ((π,π * ), (n,π * and Rydberg ...
