Synthesis of acyclic dinucleating Schiff base-pyridine and schiff base-phosphine ligands

Tetrahedron Letters, 1995
Abstract 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.

Some aspects of schiff bases of retinaldehyde

Experimental Eye Research, 1974
Abstract We have previously described an entity, which we have named Complex II, formed from retinaldehyde (RET) (any isomer) and ethanolamine-phosphoglyceride (EPG) which contains unsaturated fatty acid components. Complex II exhibits a 500-nm absorbance maximum in a spectrum similar to that of mammalian rhodopsin.

Schiff Base Complexes of Boron: Boron Complexes of Schiff Bases of 2,4-Pentanedione

Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1978
Abstract Tetra-coordinated diacetoxy-boron Schiff base derivatives of the type (AcO)2B(SB) (where SB− is the anion of the corresponding monofunctional bidentate Schiff base, SBH) have been synthesized in almost quantitative yields and in a state of sufficient purity by the equimolar ratio reactions of boric acid and Schiff bases in acetic anhydride ...

The pK of Schiff base deprotonation in bacteriorhodopsin

Biochemical and Biophysical Research Communications, 1978
Abstract Kinetic resonance Raman spectroscopy as a function of pH has been utilized to determine the pK of Schiff base deprotonation during the bacteriorhodopsin photochemical cycle. It is shown that the pK of Schiff base deprotonation is between 9.9 and 10.3, microseconds after light absorption and is >12 before photon initiation of photochemical ...

Schiff bases. Part III. Amine and ketone exchange reactions with Schiff bases

Journal of the Chemical Society C: Organic, 1968
Certain 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.

Spectroscopy of non-aromatic Schiff bases

Journal of Photochemistry, 1981
Abstract 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 ...
