Chemiluminescent Schiff bases

Journal of the Chemical Society, Chemical Communications, 1976
Although very few examples of chemiluminescent Schiff bases have been described, and attempts to extend this class of reaction have hitherto been unsuccessful, it is now shown that these compounds are generally chemiluminescent on oxidation, with reasonable efficiency.

Sulfenylation of chiral Schiff bases

Amino Acids, 1994
The purpose of this study was to examine the conditions of sulfenylation reactions of chiralα-amino esters Schiff bases to protect the chirality in theα-position.

Uranyl stabilized Schiff base complex

Chemical Communications, 2007
Uranyl Schiff base complex [(UO(2))(2)(Salpro)(OH)(Solvent)(2)] (1) in the presence of excess of ethylenediamine (EDA) does not undergo nucleophilic addition (hydrolysis) and substitution (transamination) reactions due to an extended chelation [2N, 3O + OH] by the flexible backbone.

Polymeric Schiff Bases. I. The Synthesis and Evaluation of Polymeric Schiff Bases Prepared by Schiff Base Exchange Reactions

Journal of Macromolecular Science: Part A - Chemistry, 1967
Abstract This paper compares the syntheses and the thermal stabilities of twelve related conjugated, pseudoconjugated, and nonconjugated Schiff base polymers of the general formula in which Z represents The polymers were prepared (a) by the condensation of Z(NH2)2 and p-C6 H4(CHO)2 in (1) solution and (2) as melts, and (b) by three new Schiff base ...
