报告摘要:Pincer transition-metal complexes have versatile reactivities to catalyze many organic transformations. In particular, complexes with ligand derived from tridentate pyridine-based framework exhibit interesting reactivities. We have developed a novel platform of pincer-type PN3(P)-ligands which are capable of interacting with the substrates during the reaction. We have witnessed that the seemingly small change by replacing the CH2 spacer in the pyridine-based pincer complex with a NH group has dramatically influenced the thermodynamic and kinetic properties, and in some cases the catalytic behaviors of the corresponding metal complexes. Furthermore, unprecedented ligand-centered reactivities (LCRs) were demonstrated. The σ-nucleophilicity of the N atom of the iminic arm was significantly enhanced to reach N-heterocycliccarbene-like nucleophilicity as a catalyst and a ligand. The novel LCR may open a new direction for the catalyst design.
