Nitroarylphosphines: An Overlooked Family of Ligands
- 1Chemistry, Université Laval, 1045, avenue de la Médecine, Québec, Quebec, Canada, G1V0A6
Abstract
Homoleptic tris(nitroaryl)phoshines are very rare, “explosive-looking” molecules that have until now never been fully characterized. We show that they are accessible from nitroarylphosphine oxides and are, perhaps surprisingly, sufficiently thermally stable to be handled at ambient temperature and used as ligands. We show experimentally and computationally that they display significantly modulated electronic properties and we demonstrate several examples of their coordination complexes, thus showing the nitro group is an overlooked tuning tool in phosphine coordination chemistry.
