dc.description.abstract |
Replication of a procedure to electrodeposit MoS<sub>2</sub> required use of an uncharacterized crude MoO<sub>3</sub> and ethylene glycol reaction mixture as a molybdenum precursor. Multiple attempts to replicate the desired “brown oil” resulted in isolating four crystals, with three being previously unknown products for this reaction. This evidence highlights possible identities for the molybdenum precursor responsible during this MoS<sub>2</sub> electrodeposition.<br /> A sterically bulky phosphine-imine treated with either H<sub>2</sub>O<sub>2</sub>, S<sub>8</sub>, Se<sup>0</sup> , or reacted with 9-bromofluorene followed by one equivalent of a base made four ligand precursors that can be deprotonated to act as mono-anionic ligands for a variety of metal complexes including Li-K, Al, and In. The four ligands undergo tautomerization revealing 2-4 isomers observed by <sup>1</sup>H, <sup>13</sup>C, and <sup>31</sup>P NMR spectroscopy, with two of these supported by SC-XRD analysis. Alkali metal complexes showed diverse η<sup>2</sup> to η<sup>4+6</sup> interactions with the delocalized phosphonium fluorenylide and η<sup>1</sup> /η<sup>2</sup> with 2,6-diisopropylphenyl aromatic ring systems. |
