Micelle-Enabled Palladium Catalysis for Convenient sp<sup>2</sup>‑sp<sup>3</sup> Coupling of Nitroalkanes with Aryl Bromides in Water Under Mild Conditions
The efficacy of custom
surfactant FI-750-M, designed to mimic polar
solvents such as DMF and 1,4-dioxane, has been demonstrated with the
palladium-catalyzed sp<sup>2</sup>-sp<sup>3</sup> coupling of nitroalkanes
to aryl bromides using a heteroleptic palladium catalyst under unprecedentedly
mild conditions. Optimized reaction conditions mostly provided good
yields up to gram scale, with high selectivity and functional group
tolerance for a wide scope of aryl bromides. Use of surfactant FI-750-M
makes water the gross reaction medium and enables in-flask recycling.
The behavior of the surfactant has been elucidated with DLS and cryo-TEM
measurements, and mechanistic investigations have revealed the importance
of the π-allyl ligand in the catalytic cycle
