Research Description

John Hartwig is the Henry Rapoport Chair in Organic Chemistry. Professor Hartwig's research group focuses on the discovery and understanding of new reactions of organic compounds catalyzed by transition metal complexes and artificial metalloenzymes. These findings result from a combination of organic synthesis, organometallic synthesis, protein design and evolution, and mechanistic analysis of catalytic systems.

The Hartwig group is currently investigating both small-molecule catalysts and artificial metalloenzymes for selective reactions of organic molecules. These reactions include the selective catalytic functionalization of alkanes and arenes, cross-couplings to form aryl and allyl amines and ethers, α-aryl and α-allyl carbonyl derivatives, methods for the fluorination and fluoroalkylation of arenes, additions to alkenes, methods to prepare chemicals and polymers from renewable chemical feedstocks, and hydrocarbyl functionalization reactions catalyzed by artificial metalloenzymes that combine the reactivity of transition-metal catalysts with the selectivity and evolutionary potential of enzymes. His group has conducted extensive mechanistic investigations of each of these types of reactions. Through these studies, they have revealed several new classes of organometallic reactions, including reductive eliminations, discrete compounds that functionalize alkanes, unusual three-coordinate arylpalladium complexes that are intermediates in cross-coupling, the first compounds that oxidatively add ammonia to form monomeric products, and the first transition-metal amido and alkoxo complexes that insert unactivated alkenes. In addition to these research activities he has authored a leading textbook in organometallic chemistry, titled Organotransition Metal Chemistry: From Bonding to Catalysis.

Process Converts Polyethylene Bags, Plastics to Polymer Building Blocks

A new process developed at the University of California, Berkeley, and Lawrence Berkeley National Laboratory could change the way polyethylene plastics — in particular, the ubiquitous plastic bag that blights the landscape — are notoriously recycled.

Synthetic biology moves into the realm of the unnatural

A collaboration between synthetic chemists and synthetic biologists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory has now overcome that hurdle, engineering bacteria that can make a molecule that, until now, could only be synthesized in a laboratory.

Upcycling: Turning plastic bags into adhesives

While many cities and eight states have banned single-use plastics, bags and other polyethylene packaging still clog landfills and pollute rivers and oceans. One major problem with recycling polyethylene, which makes up one-third of all plastic production worldwide, is economic: Recycled bags end up in low-value products, such as decks and construction material, providing little incentive to reuse the waste.

Alkylamines are one of the most useful compounds in a chemist’s bag of tricks. Pharmaceuticals, agrochemicals, and polymers often contain these functional groups.

Scientists finally crack nature’s most common chemical bond

The most common chemical bond in the living world — that between carbon and hydrogen — has long resisted attempts by chemists to crack it open, thwarting efforts to add new bells and whistles to old carbon-based molecules.

Researchers awarded Wolf Prizes in agriculture, chemistry

Has a UC Berkeley chemistry lab discovered the holy grail of plastic recycling?

Los Angeles Times

Susanne Rust

"But new research from a team of chemists at UC Berkeley suggests a glimmer of hope when it comes to the thorny problem of recycling plastics — one that may allow us to have our cake, and potentially take a very small bite, too." This research was first featured on UC Berkeley News.
