"They can be used to discover new medicines," he added. An example of an anti-Bredt olefin. Such molecules were thought for 100 years to be impossible to synthesize. An example of an anti-Bredt ...

Scientists have just broken a 100-year-old chemistry rule and synthesized a type of 3D, unstable molecule called an anti-Bredt olefin. When you purchase through links on our site, we may earn an ...

According to Bredt's rule, double bonds cannot exist at certain positions on organic molecules if the molecule's geometry deviates too far from what we learn in textbooks. This rule has ...

Want to now add a second connection to one of the carbons at either end of your bridgehead to form an organic double bond known as an olefin? Bredt would have said sorry, you're out of luck.

Organic chemist Neil A. Garg and his team at the University of California, Los Angeles, love testing the limits of what molecules can do. Their latest paper upends Bredt’s rule, a 100-year-old ...

Molecules that deviate from this geometry are uncommon. The rule in question, known as Bredt's rule in textbooks, was reported in 1924. It states that molecules cannot have a carbon-carbon double ...
