On October 15, 2014, Ghaffari, Behnaz; Preshlock, Sean M.; Plattner, Donald L.; Staples, Richard J.; Maligres, Peter E.; Krska, Shane W.; Maleczka, Robert E.; Smith, Milton R. published an article.Electric Literature of 1349171-28-3 The title of the article was Silyl Phosphorus and Nitrogen Donor Chelates for Homogeneous Ortho Borylation Catalysis. And the article contained the following:
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. The experimental process involved the reaction of 2-(2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)pyridine(cas: 1349171-28-3).Electric Literature of 1349171-28-3
