Zirconocene‐Mediated Radical Hydrophosphination

https://doi.org/10.1002/ejic.202300341

Javier‐Jiménez, Diego R.; Novas, Bryan T.; Waterman, Rory (July 2023, European Journal of Inorganic Chemistry)

Abstract Hydrophosphination activity has been solicited from the parent and decamethyl zirconocene dichloride compounds, Cp₂ZrCl₂and Cp*₂ZrCl₂. Given recent reports of photocatalytic hydrophosphination, these compounds were irradiated in the near ultraviolet (UV) as precatalysts resulting in the successful hydrophosphination of styrene substrates and activated alkenes. Irradiation appears to induce homolysis of the Cp or Cp* ligand, resulting in radical hydrophosphination. Successful detection of this radical reactivity was achieved by monitoring for EPR signals within situirradiation, a methodology proving to be general for the determination of radical versus closed‐shell reactivity in transition‐metal photocatalysis.
