A combination of derivatization with charged substrates and electrospray‐ionization mass spectrometry is used to fish out the active species in a catalytic reaction. The observed species in the mass spectrometer corresponds to the resting state of the catalyst. Data for the ring‐opening metathesis polymerization (ROMP) of norbornene by (Cy 3 P) 2 Cl 2 Ru=CHPh (Cy=cyclohexyl) are used to illustrate the method.
