Two-state reactivity in C–H activation by a four-coordinate iron(0) complex #chempaperaday 278

There is some debate on C-H activation by iron complexes. People debate on which oxidation state is "active". Here the authors suggest that the spin state is also important. They have some structural and experimental evidence. Nice work.
