Tripod Immobilization of Triphenylphosphane on a Silica-Gel Surface to Enable Selective Mono-Ligation to Palladium: Application to Suzuki-Miyaura Cross-Coupling Reactions with Chloroarenes
resulting in the selective formation of a 1:1 metal–phosphane species that is free from unfavorable steric repulsions caused by the silica surface. Heterogeneous Pd catalysts created in this manner enabled room‐temperature Suzuki–Miyaura cross‐coupling reactions with unactivated chloroarenes, despite the moderate electronic and steric nature of the Ph3P‐based ligands. These catalysts also showed potential
