Scientists have broken a 100-year-old chemistry rule to synthesize a class of molecules previously thought to be too unstable to form.
The anti-Bredt molecules fall into a class of compounds known as olefins. Olefins have at least one double bond — a strong chemical bond made from two pairs of electrons — connecting two carbon atoms. Each of those carbon atoms usually lies in the same 2D plane as the other atoms to which it's bonded.

Because the anti-Bredt olefins are unstable and highly reactive, the team wasn't able to isolate them directly in the new study.
