Ir catalysts supported by ortho-(diisopropylsilyl)(di-p-tolylphosphino)benzene bidentate ligand that contains P- or N-donors, effects ortho-borylations for a range of substituted aromatics E.g., reaction of C6H5CO2Me with bis(pinacolato)diboron (B2pin2) in the presence of 1.25 mol% [Ir(OMe)(cod)]2/ 2.5 mol% (p-tol)2PC6H4-2-(SiHiPr2) in THF at 80° to give 72% yield of Me 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate. The substrate scope is broad, and the modular ligand synthesis allows for flexible catalyst design.
