Abstract Tricarbonylchromium(0) complexes of sulfur, phosphorus, silicon, iodine, tin and carbon substituted (S )‐(α‐methylbenzyl)dimethylamines are oxidized by dimethyldioxirane to enantiomerically pure tricarbonylchromium(0) complexes of substituted styrenes; the reactions proceed via a chemoselective oxidation of the tertiary amines to their N ‐oxides, one of which was isolated, and a subsequent Cope reaction.
