Abstract
Abstract The synthesis of NHC-PdCl 2-3-chloropyridine (NHC= N-heterocyclic carbene) complexes from readily available starting materials in air is described. The 2, 6- diisopropylphenyl derivative was found to be highly catalytically active in alkyl–alkyl Suzuki and Negishi cross-coupling reactions. The synthesis, ease-of-use, and activity of this complex are substantial improvements over in situ catalyst generation and all current Pd– ...
