Fascinating @science.org paper for chemsky from Ryan Shenvi’s group this week, where instead of making cyclopropane from a carbene and an olefin, they make it from three separate differentially reactive C1 sources in an iron-catalyzed sequence

Iron-catalyzed [1+1+1] cyclopropanation by sequential coupling of an ester to two carbenes
Traditional precious metal catalysis benefits from well-characterized inner-sphere elementary steps in which a single complex binds and unites substrates at the metal center. By contrast, base metal c...
