A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...

Chemists have developed a straightforward method to convert common chemicals like carboxylic acids, alcohols, and alkanes directly into valuable alkenes. Chemists from the National University of ...

Although many organisms respond to light, very few enzymes inside those organisms use light directly as an energy source for catalysis. Researchers now report a new light-driven enzyme: Christened ...

A new cobalt catalyst designed by Paul Chirik and coworkers at Princeton University gives chemists two mechanisms for the price of one. The team’s alkene hydrogenation reaction runs differently ...
