Table 2: List of \({}^{1}\)H Nuclear Magnetic Resonance (NMR) peaks recorded in CDCl\({}_{3}\) from all samples produced, which allows the correct identification of compounds. Tetramethylsilane (TMS) was used as a reference and is assigned the value of 0 ppm. The peak position is reported in the peak section and the coupling in between brackets (s = singlet, t = triplet, m = multiplet).
