Researchers have produced the first “naked” aryl anion in solution—a carbanion not linked to counterions or stabilized by hydrogen bonding. Until now, many chemists believed such a species couldn’t ...

Professor Diego Peña, a chemist at the University of Santiago de Compostela and co-author of the paper, explains the significance: “At first the rearrangement was simply considered a curiosity, but in ...

Robert G. Bergman is a preeminent organic and organometallic chemist who has made a large number of groundbreaking contributions to chemical science, especially hydrocarbon chemistry. “His discoveries ...

The Bergman cyclization is an eponymous chemical reaction in which an enediyne is converted into a benzene derivative via a diradical intermediate. Now, Leo Gross and co-workers have shown that it is ...
