Path A depicts an intermolecular reaction between an aldehyde and olefin using stoichiometric amounts of an olefin metathesis catalyst. Path B depicts an intermolecular, two-step reaction sequence.

Olefin metathesis is already regarded as an important way to make carbon-carbon bonds, but the reaction could become even more practical, thanks to a new, highly active, water-soluble catalyst. In ...

Organometallic catalysts are useful in lab research, and some are used industrially. They generally don’t work well in living cells. But researchers have now assembled an artificial enzyme with an ...
