UCLA Chemists Have Created “Impossible” 3D Bonds That Shouldn’t Exist

UCLA chemists proved that some of chemistry’s oldest rules can be broken—and new molecules emerge when they are.

A Rule of Chemistry Stood for 100 Years. Now, Scientists Have Broken It—Twice.

Researchers synthesized weird molecules that exist in three dimensions, breaking Bredt's rule and helping to develop future ...

A year after undermining Bredt's rule, scientists make cage-shaped, double-bonded molecules that defy expectations

Organic chemistry is packed with rules about structure and reactivity, especially when it comes to making and breaking chemical bonds. The rules governing how these bonds, which hold atoms together in ...
