Nitromethane (1) upon treatment with Carbon disulfide (2) under ice cold condition in presence of dry methanol/Potassium hydroxide gave dipotassium salt of nitroketene dithioacetal (3). Further treatment of dipotassium salt (3) with transition metal zinc furnished NKDA-Zn complex (4). The structure of the synthesized complex was characterised using UV, IR, 1H, 13C-NMR spectral, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) evidences. The electro-catalytic activity of the modified SPCE of NZ towards the detection of L-Met was carried out. The electrochemical behavior of the NZ/SPCE were examined using cyclic voltammetry, and differential pulse voltammetry (DPV).
