A Sterically Constrained Tricyclic PC3 Phosphine: Coordination Behavior and Insertion of Chalcogen Atoms into P-C Bonds

摘要

A tricyclic phosphine has been generated that has a rigid molecular backbone with the P atoms exclusively bound to C(sp(2)) atoms as well as a very large Tolman angle and buried volume. It is an interesting new ligand in coordination chemistry (Au, Pd complexes) and shows unusual insertion reactions into its endocyclic P-C bonds facilitated by its inherent molecular strain.
