Abstract

A tricyclic phosphine has been generated that has a rigid molecular backbone with the P atoms exclusively bound to C(sp² ) 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.

Keywords: Tolman angle; bulky ligands; gold; phosphines; phosphoranes.
