On the basis of analytical and experimental data, the Schiff bases were coordinated to Cu(II) ion with four donor atoms, two imine nitrogens and two deprotonated alkoxy-oxygen atoms.
This indicates that the fillers can facilitate the cure reactions to occur at earlier temperature, due to the catalytic action of hydroxyl and free amino groups of chitosan moiety as well as the imine groups of PANI grafted chains.
The synthetic strategy for the synthesis of imines 8a-g has been described in the Scheme 3, involves reaction of acid hydrazide 1 with thiosemicarbazide to give first on a product it is 1-((5-amino-1,3,4-thiadiazol-2-yl)methyl)-3H-benzo[f]chromen-3-one 7, which is considered as starting material for the synthesis of imines 8a-f and 8g by its reaction with substituted aldehydes or isatin as shown in Scheme 3.

Metal complexes of imine bases derived from substituted aldehydes and heterocyclic compounds containing nitrogen, sulfur, and/or oxygen as ligand atoms are of interest as simple structural models of more complicated biological systems [16].
The formation of imines as by-products of the benzoxazine polymerization process has been hypothesized by several authors [31, 32].
L-Cys reacts with acetaldehyde to generate imine (Figure 6), which is harmless to the human body and can be directly excreted, making L-Cys protective to organisms [20, 25].
