Shining New Light on an Old Problem: Retooling MALDI Mass Spectrometry for Organotransition‐Metal Catalysis

Getting the air out: A bottleneck in transition-metal chemistry is the laborious process of identifying organometallic molecules. Anaerobic, charge-transfer MALDI-MS is a powerful new tool for observation of these reactive, often fragile species. Examples are drawn from catalysts relevant to olefin metathesis, hydrogenation, polymerization, and cyclopropanation. IMes=N,N′-bis(mesityl)imidazol-2-ylidene.
