An Efficient Indenyl-Derived Phosphine Ligand for the Suzuki-Miyaura Coupling of Sterically Hindered Aryl Halides.

An air-stable aryl substituted indenyl phosphine used in combination with Pd(OAc)2 provides a highly efficient catalyst for the Suzuki–Miyaura cross-coupling reaction of sterically hindered aryl halides with aryl boronic acids.
