Chemists broke a 100-year-old rule to make extremely unstable molecules
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.
First successful synthesis of elusive antibiotic compounds since their discovery 50 years ago
Back in 1974, German researchers discovered peculiar chemical compounds, present as red pigments in soil bacteria from a ...
