Oxidation Processes in a Phosphine-Thiocarbohydrazone Ligand
Chemistry Proceedings(2022)
摘要
In this work, we isolated a pentadentate [P2N2S] phosphine-thiocarbohydrazone ligand H2L with a bulky phosphine group in both linker domains that undergoes an oxidation process in solution. This ligand was synthesized by a direct reaction between two equivalents of 2-diphe-nylphosphinebenzaldehyde and one equivalent of thiocarbohydrazide. Two types of crystals de-rived from this ligand were obtained and studied using X-ray diffraction spectroscopy. One structure corresponds to the monooxidized ligand H2L(O) while the other indicates a dioxidation of the compound, H2L(OO).
