Chemical equation presented Expanding the horizons of ArPPh2: New applications of triarylphosphane ligands are presented. The Pd-L1 and Pd-L2 complexes offer exceptionally high activity in Suzuki-Miyaura cross-couplings of aryl chlorides. The extremely congested synthesis of tetraortho-substituted biaryl compounds is achieved for the first time by simply using triarylphosphane ligands.

A family of indolyl phosphine ligands was applied to Suzuki-Miyaura cross-coupling of aryl tosylates. Catalyst loading can be reduced to 0.2 mol % for coupling of nonactivated aryl tosylate. A challenging example for room temperature coupling is realized. The scope of this highly active Pd/L2 system can be extended to other boron nucleophiles, including trifluoroborate salts and boronate esters. The ligand structural comparisons toward the reactivity in tosylate couplings are also described.
