Electrospray ionization mass spectrometry (ESI‐MS) was used for the first time to study the deactivation pathways of Jørgensen–Hayashi‐type catalysts modified with an ionic group in asymmetric Michael reactions. “Parasitic” oxidation and hydrolysis side reactions that poisoned the catalysts were identified. Other types of organocatalysts modified with ionic groups in various organocatalytic reactions may also be investigated by the approach described in the Full Paper by S. G. Zlotin et al. on page 6109 ff.
