The products of 1,3-dipolar cycloaddition of the nitrone-type η6-(arene)chromium tricarbonyl complexes (CO)3CrC6H5CH=N+(O−)R, where R = Me, Ph, But, with styrene and η6-(styrene)chromium tricarbonyl were obtained and characterized by a combination of physicochemical methods. This type of reactions proceeded with very high regio- and stereoselectivity to exclusively form cis-2,3,5-tri-substituted isoxazolidines.
