Overview of scholarly research/creative activity: Chemical catalysis is involved in over 80% of industrial chemical production, and many current catalytic processes rely on expensive and rare metal catalysts. To create more sustainable industrial methods, the Liberman-Martin group is creating new metal-free catalysts as inexpensive and earth abundant catalyst alternatives.
Specific projects working on: All of our group's research involves manipulation of air-sensitive compounds. Skills in air-free synthesis are highly desirable in organic and inorganic chemistry graduate programs, the pharmaceutical industry, and battery and semiconductor manufacturing.
Our group is interested in the synthesis of new metal-free catalysts for the sustainable production of chemicals, polymers, and fuels.
Much of our current research is on understanding the electronic properties and catalytic activity of exceptionally electron-rich carbon(0) species. The carbon(0) catalysts we use are called carbodiphosphoranes, which feature two-coordinate carbon flanked by two phosphorus donors. The central carbon of the carbodiphosphorane is strongly nucleophilic.
We are investigating the ability of these catalysts to promote the addition of hydrogen–boron bonds across C=O and C=N bonds. We have found that these carbodiphosphoranes also catalyze polymerization reactions. These polyesters are important in tissue engineering and drug delivery as a result of their excellent materials properties, biocompatibility, and facile degradation.
We also have projects looking at germanium and zinc compounds as catalysts for organic reactions.
