Catalysis

How can metal complexes be used to make P-C bonds for the preparation of valuable chiral phosphine ligands?

We have developed several new catalytic reactions for asymmetric synthesis of chiral phosphines. These include Pt-catalyzed asymmetric hydrophosphination of activated olefins, Pd-catalyzed asymmetric phosphination of aryl halides, and Pt-catalyzed asymmetric alkylation of secondary phosphines.

Research goals:

1. Develop these reactions for practical synthesis of enantiomerically pure chiral phosphines.

2. Understand the mechanism of P-C bond formation to develop better catalysts.

3. Use the new phosphines in asymmetric catalysis.

Is this organic chemistry, or inorganic chemistry? Yes.  Both.  Students who worked on these projects now have positions teaching either one of these subjects.

Synthesis

We make molecules.  Organic (especially organophosphorus), organometallic, and inorganic.

Check out these papers for more.

2. Characterization of phosphines and metal complexes relies on NMR and X-ray crystallography (thanks to Arnie Rheingold and coworkers at the University of California, San Diego).

Materials

Materials projects have included the synthesis of gold nanoparticles, smaller gold cluster molecules, and block copolymer/metal nanoparticle composites (collaboration with Barney Grubbs).  In a newer NSF-REU project, we are studying structure-property relationships in luminescent metal complexes. See these papers for more.
