Trioctylphosphine oxide (TOPO) is a synthetic compound belonging to the organophosphorus family. Trioctylphosphine oxide finds its primary applications as a phase transfer catalyst and ligand in organometallic chemistry. Moreover, it plays a role in the synthesis of polymers and functions as a surfactant in the realm of nanotechnology. The properties of trioctylphosphine oxide stem from its ability to act as a Lewis base, enabling the formation of coordinate covalent bonds with Lewis acids. This attribute allows Trioctylphosphine oxide to function as a catalyst in numerous reactions, including nucleophilic substitution, elimination, and condensation reactions. Additionally, its surfactant properties allow it to reduce the surface tension of solutions and enhance compound solubility.
