Reduction Mechanism Investigation Of Some Schiff Base Podand Derivatives At Glassy Carbon Electrode By Using Electrochemical Techniques
Electrochemical reduction mechanism of some salicylaldimine podands derived from salicylaldehyde and diamines having general formula of HO-C6H4-CH=N-R-N=CH-C6H4-OH [R = ‒, (CH2)6, (CH2CH2)2NH, (CH2CH2OCH2)2], namely N,N’-bis(salicylidene)-diamine (BSA), N,N’-bis(salicylidene)-1,6-hexanediamine (BSH...

| Summary: | Electrochemical reduction mechanism of some salicylaldimine podands derived from salicylaldehyde and diamines having general formula of HO-C6H4-CH=N-R-N=CH-C6H4-OH [R = ‒, (CH2)6, (CH2CH2)2NH, (CH2CH2OCH2)2], namely N,N’-bis(salicylidene)-diamine (BSA), N,N’-bis(salicylidene)-1,6-hexanediamine (BSH), 1,7-bis(2-hydroxybenzyl)-1,4,7-triazaheptane (BST), 1,10-bis(2-hydroxybenzyl)-4,7-dioxa–1,10-diazadecane (BDD), respectively, were investigated by using various electrochemical techniques in 0.1 M tetrabutylammonium tetrafluoroborate (TBATFB) in acetonitrile (MeCN) at a glassy carbon (GC) electrode. Schiff base podand derivatives show cyclic voltammetric (CV) irreversible one-electron reduction peaks at about -1.82 V, -2.20 V, -2.14 V and -2.10 V at a scan rate of 0.1 V/s at GC electrode (vs. Ag/Ag ), respectively. The reaction mechanism was investigated by CV and decided to be electrochemical-chemical (EC) route and this mechanism was verified by digital simulation. The number of electrons transferred (n) and diffusion coefficients (D) of the compounds were determined using an ultramicroelectrode (UME) by CV, chronoamperometry (CA) and hydrodynamic voltammetry. |
