Electrochemical Synthesis of some Polyazomethines by Organometallic Reductive Catalysis

Abstract

Three monomers with preformed Schiff base structures and ~nal bromine atoms were synthesized: N, N°-bis(4-bromophenyl)-terephthaldiimine (I), N, N°-bis(4-bromobenzylidene)-benzene-1,4-dia-mine (II) and N-(4-bromobenzylidene)-4°-bromoaniline (III). All these compounds were used to prepare polyazomethines by dehalogenative coupling reactions via organometallic reductive catalysis (Ni0.bipy). The monomers and corresponding polymers were characterized by spectral methods (FT-IR, 1HNMR, UV-Vis) as well as by thermal analysis

Synthesis, characterization, conductivity and antimicrobial study of a novel thermally stable polyphenol containing azomethine group

“…Schiff base polymers have been synthesized using electrochemical [10] and chemical [11,12] methods. Oxidative polycondensation reactions carried out using NaOCl, H 2 O 2 and O 2 oxidants are one of the most widely used method for the chemical polymerization.…”

Synthesis and Study of Arylenevinylene and Aryleneimine-Type Polymers Containing N-Hexyl-3.6-Carbazolyl Groups

“…Recently, the electrosynthesis of some polymers by dehalogenative organometallic polycondensation using a zerovalent nickel complex, Ni 0 L m has been reported [8][9][10][11]. A complex type NiBr 2 2(bipy) (where bipy is 2,2 3 -bipyridine) was used as a catalytic precursor in order to synthesize various polyconjugated compounds.…”
