Phosphorus-Containing Hybrid Calixphyrins: Promising Mixed-Donor Ligands for Visible and Efficient Palladium Catalysts

摘要

There has been a great deal of interest in the coordination chemistry of phosphorus-containing macrocyclic ligands,because the metal center is supported and stabilized by multidentate platforms,and various coordination environments are available by changing the components of the macrocycles.However,the potential utility of this class of ligands in transition metal catalysis has not been explored much,partly because of a lack of information on the relationship between their structural properties and their catalytic activities.
