Chromium carbenes are used in organic synthesis as reagents to obtain molecules of biological interest. In this work a particle beam (PB) coupled liquid chromatography/mass spectrometry (LC/MS) system was used for the characterization of a mixture of chromium aminocarbene complexes. Three of them are new compounds. The separation of the examined complexes was performed using normal‐phase chromatography. The acquisition of electron ionization, positive‐ion and negative‐ion chemical ionization mass spectra of the eluates was accomplished. The capability of PB LC/MS technique in the on‐line characterization of organometallic compounds is highlighted. In addition, the fragmentation patterns of all the compounds considered are discussed. © 1997 John Wiley & Sons, Ltd.
