Synthesis and NMR characterization of new tert-Butyl thiosemicarbazone compounds and corresponding palladium complexes

This work shows the synthesis and characterization of a series of tert-Butyl thiosemicarbazone compounds, based on the 4-tert-Butyl-3-thiosemicarbazide substrate. The corresponding palladium complexes of this series of ligands were obtained via a reaction with Palladium(II) Chloride. After synthesis and purification, the 1H NMR and 13C NMR spectra were obtained using a 500 MHz NMR spectrometer. Experimental data was observed using 2D NMR techniques, such as, HSQC (hetero-nuclear single quantum coherence) 1H-13C NMR and HSQC 1H-15N NMR to give evidence for the structures of these new compounds.
