Chemists Break Decades-Old Barrier in Molecule Building

Topic: Chemistry

Researchers at the University of Wisconsin-Madison have developed a new way to build complex molecules. They release electrons directly into solution, allowing for more control over reactions. This breakthrough could lead to new life-saving drugs and materials.

Chemists use special molecules called catalysts to help build complicated structures like medicines and advanced materials. One of the most useful tools is single-electron transfer, which helps activate molecules that wouldn't normally react. However, for decades, chemists have faced a problem: when two molecules compete for an electron, it usually goes to the one that's easiest to reduce.

A team led by Zachary Wickens at the University of Wisconsin-Madison has found a solution to this problem. They developed a catalyst that releases electrons directly into the surrounding solution. This is different from traditional methods, which try to control which molecule gets the electron. The free electron then attaches itself to the first molecule it encounters, even if it's not the preferred one.

The researchers worked with teams at Colorado State University and the University of Colorado Boulder to understand why this new approach works. They found that the crucial selection happens after the electron transfer has occurred. The desired molecule can continue along the pathway that produces the final product, while the other molecule returns to its original state.
