So, once you make that carbon-boron bond, there are many different compounds that can be made. One potential application, Hartwig said, is altering natural compounds — chemicals from plants or animals that have useful properties, such as antibiotic activity — to make them better.

Many pharmaceutical companies today are focused on biologics — organic molecules, such as proteins, used as drugs — that could also be altered with this reaction to improve their effectiveness.

He said that chemists could also add new chemical groups to the ends of organic molecules to prep them for polymerization into long chains never before synthesized. Chemists have long tried to make targeted additions to carbon-hydrogen bonds, a reaction referred to as C-H activation.

One still unachieved dream is to convert methane — an abundant, but often wasted, byproduct of oil extraction and a potent greenhouse gas — into an alcohol called methanol that can be used as a starting point in many chemical syntheses in industry.

Robert Bergman, the Gerald E. Branch Distinguished Professor, emeritus, in the Department of Chemistry. In , Robert Bergman, now a UC Berkeley professor emeritus of chemistry, first showed that an iridium atom could break a C-H bond in an organic molecule and insert itself and an attached ligand between the carbon and hydrogen.

There is also a very good book about this, that is not highly mathematical; The Self-Made Tapestry Pattern formation in nature By Philip Ball I once gave a lecture to the Concrete Society about cracks in concrete, and compared them with cracks in wood and elsewhere, with lots of powerpoint pictures.
