Gas-Liquid Chromatography-Mass Spectrometry of Some Arene Tricarbonylchromium Complexes

Abstract

The gas-liquid chromatography-mass spectrometry of a number of arene tricarbonylchromium complexes has been investigated. The combined technique readily demonstrates that substituted benzene π-complexes survive the analysis intact, but a closely related compound, the tricarbonylchromium complex of 2,3-dimethylnaphthalene, has proven to be thermally unstable both on the column and in the molecular separator.
