Chemists have explained the structure of a non-classical carbocation. They have captured the 2-norbornyl cation as a crystal and determining beyond doubt the structure of this unusual and instable ...

For more than a decade in the middle of the 20th century, chemists debated exactly what "carbocations" -- molecules with a positively charged carbon atom -- looked like. What is known as the ...

Researchers report they have discovered a chemical reaction that might someday be used to process petroleum into useful compounds. For more than a decade in the middle of the 20th century, chemists ...
