摘要:
N-Heterocyclic carbene ligands derived from C-2-symmetric diamine with naphthyl side chains are introduced as chiral monodentate ligands, and their palladium complexes (NHC)Pd(cin)Cl are prepared. These compounds exist as a mixture of diastereomers, and the palladium complexes can be successfully separated. When used in the asymmetric Suzuki-Miyaura and Kumada coupling, chiral biaryls can be obtained in high yield and moderate selectivity.
