Chemists at UCLA are showing that some of organic chemistry’s most famous “rules” aren’t as unbreakable as once thought. By creating bizarre, cage-shaped molecules with warped double bonds—structures ...

Scientists have long known that protons hop along hydrogen-bond pathways in these systems. What they couldn't pin down was ...

A repurposed reagent can stereoselectively insert nitrogen into C–H bonds, even those unactivated by nearby functional groups ...
